Arbitrary (or unscientific) Method: It’s a method of seeking answers to question consists of imagination, opinion, blind belief or impression. 2. Young defines Research as “a scientific undertaking which, by means of logical and systematic techniques”. 3. Kerlinger defines research as a “systematic, controlled, empirical and critical investigation of hypothetical propositions about the presumed relations among natural phenomena”. 4. Research is a scientific Endeavour. 5. The scientific method is based on certain “articles of faith. 6. Ethical Neutrality: “Science never imposes anything, science states. Science aims at nothing but making true and adequate statements about its object.” 7. Pure Research: It is undertaken for the sake of knowledge without any intention to apply it in practice, e.g., Einstein’s theory of relativity, Newton’s contributions, Galileo’s contribution, etc 8. Applied Research: It is carried on to find solution to a real-life problem requiring an action or policy decision. It is thus problem-oriented and action-directed. It seeks an immediate and practical result, e.g., marketing research carried on for developing a news market or for studying the post-purchase experience of customers. 9. Exploratory Research: It is also known as formularize research. 10. Descriptive Study: It is a fact-finding investigation with adequate interpretation. It is the simples type of research. 11.Diagnostic Study: It is similar to descriptive study but with a different focus. It is directed towards discovering what is happening, why it is happening and what can be done about. It aims at identifying the causes of a problem and the possible solutions for it. 12.Evaluation Studies: It is a type of applied research. 13.Action Research: It is a type of evaluation study. 14.It includes six major steps: diagnosis, sharing of diagnostic information, planning, developing change programme, initiation of organizational change, implementation of participation and communication process, and post experimental evaluation. 15.According to a famous Hudson Maxim, “All progress is born of inquiry.

Generalization 6. Verifiability 7. Logical reasoning process UNIT: 2 1. According to Stevens, measurement is “the assignment of numerals to objects or events according to rules.” 2. Campbell defines measurement as “the assignment of numbers to represent properties.” 3. In the words of Torgerson, measurement is “the assignment of numbers to objects to represent amounts or degrees of a property possessed by the entire object. 4. Measurement may be classified into four different levels, based on the characteristics of order, distance and origin. • Nominal measurement • Ordinal measurement • Interval measurement • Ratio measurement


5. There are two dimensions of reliability – stability and equivalence or nonvariability. 6. Reliability can be improved in three ways – 7. 1) By reducing the external sources of variation. This in turn can be achieved by standardizing the conditions under which measurement is carried out, by employing trained investigators and by providing standard instructions. 2) By making the measuring instrument more consistent internally, through an analysis of the different items 3) By adding more number of items to the measuring instrument, in order to increase the probability of more accurate measurement. 8. Research is concerned with the measurement of objects. F 9. A person’s emotions may be directly observed. F 6

RESEARCH METHODOLOGY MB 0051 10. Linearity means that the measuring scale should not measure more than one characteristic at a time. F 11. The problem of extraneous variables arises in the case of construct validity. F 12. Validity is determined mainly by predictive validity.

RESEARCH METHODOLOGY MB 0051 UNIT: 4 1. According to Theodor son and Theodor son, “a hypothesis is a tentative statement asserting relationship between certain facts. Kerlinger describes it as “a conjectural statement of the relationship between two or more variables”. 2. Black and Champion have described it as “a tentative statement about something, the validity of which is usually unknown”. 3. Characteristics of Good Hypothesis : a. Conceptual Clarity b. Specificity c. Testability d. Availability of Techniques e. Theoretical relevance f. Consistency g. Objectivity h. Simplicity 4. Null hypothesis = H0 and Alternative hypothesis = Ha 5.

6. In case we take the significance level at 5%, then this implies that H0 will be rejected when the sampling result (i.e., observed evidence) has a less than 0.05 probability of occurring if H0 is true. 7.

8. A two-tailed test rejects the null hypothesis if, say, the sample mean is significantly higher or lower than the hypnotized value of the mean of the population. 9. A one-tailed test would be used when we are to 10.test, say, whether the population mean in either lower than or higher than some hypothesized value. 11. The factors that affect the level of significance are: a. The magnitude of the difference between sample ; b. The size of the sample; 8

RESEARCH METHODOLOGY MB 0051 c. The variability of measurements within samples; d. Whether the hypothesis is directional or non – directional (A directional hypothesis is one which predicts the direction of the difference between, say, means). In brief, the level of significance must be adequate in the context of the purpose and nature of enquiry. 12.Z-test is based on the normal probability distribution and is used for judging the significance of several statistical measures. 13.T-test is based on t-distribution and is considered an appropriate test for judging the significance of sample mean or for judging significance of difference between the two means of the two samples in case of samples when population variance is not known (in which case we use variance of the sample as an estimate the population variance). 14.X2-test is based on chi-square distribution and as a parametric test is used for comparing a sample variance to a theoretical population variance is unknown. 15.F-test is based on f-distribution and is used to compare the variance of the two-independent samples. This test is also used in the context of variance (ANOVA) for judging the significance of more than two sample means at one and the same time. 16.Null is a positive statement. 17. Type II error is accepting a statement that is false. 18. Hypothesis is tentative statement.

Unit: 5 1. Jahoda and Destsch and Cook describe, “A research design is the arrangement of conditions for collection and analysis of data in a manner that aims to combine relevance to the research purpose with economy in procedure. 2. Extraneous variable: The independent variables which are not directly related to the purpose of the study but affect the dependent variable are known as extraneous variables. 3. Confounded relationship: The relationship between dependent and independent variables is said to be confounded by an extraneous variable, when the dependent variable is not free from its effects. 4. Treatments: Treatments are referred to the different conditions to which the experimental and control groups are subject to. In the example considered, the two treatments are the parents with regular earnings and those with no regular earnings. 5. There are a number of crucial research choices, various writers advance different classification schemes, some of which are: 1. Experimental, historical and inferential designs (American Marketing Association). 2. Exploratory, descriptive and causal designs (Selltiz, Jahoda, Deutsch and Cook). 3. Experimental and expost fact (Kerlinger) 4. Historical method, and case and clinical studies (Goode and Scates) 5. Sample surveys, field studies, experiments in field settings, and laboratory experiments (Festinger and Katz) 9

RESEARCH METHODOLOGY MB 0051 6. Exploratory, descriptive and experimental studies (Body and Westfall) 7. Exploratory, descriptive and casual (Green and Tull) 8. Experimental, „quasi-experimental designs‟ (Nachmias and Nachmias) 9. True experimental, quasi-experimental and non-experimental designs (Smith). 10. Experimental, pre-experimental, quasi-experimental designs and Survey Research (Kidder and Judd). hose different categorizations exist, because „research design‟ is a complex concept. In fact, there are different perspectives from which any ven study can be viewed. They are: 1. The degree of formulation of the problem (the study may be exploratory or formalized) 2. The topical scope-breadth and depth-of the study (a case or a statistical study) 3. The research environment: field setting or laboratory (survey, laboratory experiment) 4. The time dimension (one-time or longitudinal) 5. The mode of data collection (observational or survey) 6. The manipulation of the variables under study (experimental or expost factor) 7. The nature of the relationship among variables (descriptive or causal) 6. Three methods in the context of research design for such studies are talked about: a. The survey of concerning literature b. Experience survey c. Analyses of ‘insight-stimulating’ examples are 7. Research design in case of descriptive and diagnostic research studies: 1. Formulating the objective of the study 2. Designing the methods of data collection 3. Selecting the sample 4. Collecting the data 5. Processing and analyzing the data 6. Reporting the findings. 8. Professor Fisher has enumerated three principles of experimental designs: 1. The principle of replication 2. The principle of randomization 3. Principle of local control 9. Formal Experimental Designs: 1. Completely randomized design (CR design): It involves only two principle viz., the principle of replication and randomization. 2. Randomized block design (RB design): It is an improvement over the C Research design. In the RB design the principle of local control can be applied along with the other two principles. 3. Latin square design (LS design): It is used in agricultural research. The treatments in a LS design are so allocated among the plots that no treatment occurs more than once in any row or column. 4. Factorial design: It is used in experiments where the effects of varying more than one factor are to be determined. They are especially important in several economic and social phenomena where usually a large number of factors affect a particular problem. 10. A research design is a logical and systematic plan. T 10

RESEARCH METHODOLOGY MB 0051 11. Exploratory research studies are also called formularize research studies. T 12. Descriptive research is concerned with describing the features of a particular individual or group. T 13. A research design is a logical and systematic plan prepared for directing a research study. Unit: 6 1. Case study is a method of exploring and analyzing the life of a social unit or entity, be it a person, a family, an institution or a community. The aim of case study method is to locate or identify the factors that account for the behavior patterns of a given unit, and its relationship with the environment. 2. The major credit for introducing case study method into social investigation goes to Frederick Leplay. Herbert Spencer was the first social philosopher who used case study in comparative studies of different cultures. William Healey used case study in his study of juvenile delinquency. Anthropologists and ethnologists have liberally utilized cast study in the systematic description of primitive cultures. 3. Case study of particular value when a complex set of variables may be at work in generating observed results and intensive study is needed to unravel the complexities. 4. Blummer points out that independently, the case documents hardly fill the criteria of reliability, adequacy and representativeness, 5. John Dollard has proposed seven criteria for evaluating such adequacy as follows: a. The subject must be viewed as a specimen in a cultural series b. The organic motto of action must be socially relevant. c. The strategic role of the family group in transmitting the culture must be recognized. d. The specific method of elaboration of organic material onto social behavior must be clearly shown e. The continuous related character of experience for childhood through adulthood must be stressed f. Social situation must be carefully and continuously specified as a factor. g. The life history material itself must be organized according to some conceptual framework, this in turn would facilitate generalizations at a higher level. 6. The exploratory investigator is best served by the active curiosity and willingness to deviate from the initial plan, when the finding suggests new courses of enquiry, might prove more productive. 7. Case study is a method of exploring and analyzing the life of a social unit. T 8. Case study of not particular value when a complex set of variables may be at work. F 9. In-depth analysis of selected cases is not of particular value to business research. F UNIT: 7


RESEARCH METHODOLOGY MB 0051 1. Simple random sampling technique( homogeneous) gives each element an equal and independent chance of being selected. An equal chance means equal probability of selection. 2. Stratified random sampling is an improved type of random or probability sampling. In this method, the population is sub-divided into homogenous groups or strata, and from each stratum, random sample is drawn. 3. Proportionate stratified sampling involves drawing a sample from each stratum in proportion to the latter’s share in the total population. 4. Disproportionate stratified random sampling does not give proportionate representation to strata. 5. Systematic random sampling method is an alternative to random selection. It consists of taking k th item in the population after a random start with an item from 1 to k. It is also known as fixed interval method. 6. Cluster sampling means random selection of sampling units consisting of population elements. 7. In Area sampling larger field surveys cluster consisting of specific geographical areas like districts, taluks, villages or blocks in a city are randomly drawn. 8. Multi-stage sampling is carried out in two or more stages. The population is regarded as being composed of a number of second stage units and so forth. That is, at each stage, a sampling unit is a cluster of the sampling units of the subsequent stage. 9. Double sampling and multiphase sampling refers to the subsection of the final sample form a pre-selected larger sample that provided information for improving the final selection. 10.Replicated or interpenetrating sampling involves selection of a certain number of sub-samples rather than one full sample from a population. 11.Non-probability or non random sampling is not based on the theory of probability. This sampling does not provide a chance of selection to each population element. 12.Purposive (or judgment) sampling method means deliberate selection of sample units that conform to some pre-determined criteria. This is also known as judgment sampling. 13.Quota sampling is a form of convenient sampling involving selection of quota groups of accessible sampling units by traits such as sex, age, social class, etc. it is a method of stratified sampling in which the selection within strata is non-random. 14.Snow-ball sampling is the colorful name for a technique of Building up a list or a sample of a special population by using an initial set of its members as informants. 15.Probability sampling is based on the theory of probability. It is also known as random sampling. It provides a known non-zero chance of selection for each population element. 16.A sample must be representative of the population. 17. Probability sampling technique yield representative sample. 18. accuracy is defined as the degree to which bias is absent from the sample. An accurate sample is the one which exactly represents the population. 12

RESEARCH METHODOLOGY MB 0051 19.Precision is measured by standard error. 20. A good sample must be adequate in size in order to be reliable. A part of the population is known as sample. The method consisting of the selecting for study, a portion of the ‘universe’ with a view to draw conclusions about the ‘universe’ or ‘population’ is known as sampling. 21.Sampling helps in time and cost saving. 22.Sampling has the following advantages: a.

The response rate of mail surveys is low. Hence, the resulting sample will not be a representative one. 9. Mail survey can cover extensive geographical areas. 10. Mail surveys, being more impersonal, provide more anonymity than personal interviews. 11. Mail surveys are totally free from the interviewers bias as there is no personal contact between the respondents and the investigator.

27.The transcription of data can be used to summarize and arrange the data in compact form for further analysis. The process is called tabulation. 28.Manual Tabulation

29.Computerized tabulation is easy with the help of software packages. 30.Frequency tables provide a “shorthand” summary of data. 20


32.Central tendency of the data is measured by statistical averages. Averages are classified into two groups. 1. Mathematical averages 2. Positional averages 30. Merits of Median 1. Median is easy to calculate and simple to understand. 2. When the data is very large median is the most convenient measure of central tendency. 3. Median is useful finding average for data with open-ended classes. 4. The median distributes the values of the data equally to either side of the median. 5. Median is not influenced by the extreme values present in the data. 6. Value of the median can be graphically determined. Demerits of Median • To calculate median, data should be arranged according to ascending order. This is tedious when the number of items in a series is numerous. • Since the value of median is determined by observation, it is not a true representative of all the values. • Median is not amenable to further algebraic treatment. • The value of median is affected by sampling fluctuation.

33.Mode Mode is the most repeating value of a distribution. When one item repeats more number of times than other or when two items repeat equal number of times, mode is ill defined. Under such case, mode is calculated by the formula (3 median – 2 mean). Mode is a widely used measure of central tendency in business. We speak of model wage which is the wage earned by most of the workers. Model shoe size is the mostly demanded shoe. 34.Merits of Mode 21


Mode is the most typical and frequented value of the distribution. It is not affected by extreme values. Mode can be determined even for series with open-ended classes. Mode can be graphically determined.

35.Demerits of Mode 1. It is difficult to calculate mode when one item repeats more number of times than others. 2. Mode is not capable of further algebraic treatment. 3. Mode is not based on all the items of the series. 4. Mode is not rigidly defined. There are several formulae for calculating mode. 33. Dispersion is the tendency of the individual values in a distribution to spread away from the average. 34. Dispersion is a statistical measure, which understands the degree of variation of items from the average. 35. Properties of a Good Measure of Dispersion A good measure of dispersion should be simple to understand. 1. It should be easy to calculate 2. It should be rigidly defined 3. It should be based on all the values of a distribution 4. It should be amenable to further statistical and algebraic treatment. 5. It should have sampling stability 6. It should not be unduly affected by extreme values. 36. Measures of Dispersion 1. Range 2. Quartile deviation 3. Mean deviation 4. Standard deviation 5. Lorenz curve 36.Lorenz curve is a graphical measure of dispersion. 37.Quartile deviation is defined as inter quartile range 38.

39. Merits of Quartile Deviation 1. Quartile Deviation is superior to range as a rough measure of dispersion. 2. It has a special merit in measuring dispersion in open-ended series. 3. Quartile Deviation is not affected by extreme values. 40. Demerits of Quartile Deviation 1. Quartile Deviation ignores the first 25% of the distribution below Q1 and 25% of the distribution above the Q3 22

RESEARCH METHODOLOGY MB 0051 2. Quartile Deviation is not amenable to further mathematical treatment. 3. Quartile Deviation is very much affected by sampling fluctuations. 41. Range and quartile deviation do not show any scatter ness from the average. 42. Steps for mean deviation: 1. Calculate mean, median or mode of the series 2. Find the deviation of items from the mean, median or mode 3. Sum the deviations and obtain ΣD 4. Take the average of the deviations ΣD/N, which is the mean deviation. 43. Standard deviation is the most important measure of dispersion. It satisfies most of the properties of a good measure of dispersion. It was introduced by Karl Pearson in 1893. Standard deviation is defined as the mean of the squared deviations from the arithmetic mean. Standard deviation is denoted by the Greek letter. 44. Standard deviation can be computed in two methods 1. Taking deviation from actual mean 2. Taking deviation from assumed mean. 45.

46. According to L.R. Connor, “if two or more quantities vary in sympathy so that movements in the one tend to be accompanied by corresponding movements in the other(s) they are said to be correlated”. W.I. King defined “Correlation means that between two series or groups of data, there exists some casual connection”. 47. Types of Correlation Analysis Correlation can be: • Positive or negative • Linear or non-linear • Simple, multiple or partial 48. Non-linear is called curvilinear correlation because graph of such correlation results in a curve. 49. scatter diagram: This is a graphical method of studying correlation between two variables. If the trend is downward sloping, correlation is negative.

50. PROBABLE ERROR: If the coefficient of correlation is less than Probable Error it will not be significant. If the coefficient of correlation r is more than six times the Probable Error, correlation is definitely significant. If Probable Error is 0.5 or more, it is generally considered as significant. Probable Error is estimated by the following formula. 23

RESEARCH METHODOLOGY MB 0051 51. Spearman’s Rank Correlation Method Charles Edward Spearman, a British psychologist devised a method for measuring correlation between two variables based on ranks given to the observations. This method is adopted when the variables are not capable of quantitative measurements like intelligence, beauty etc. in such cases, it is impossible to assign numerical values for change taking place in such variables. It is in such cases rank correlation is useful. Spearman's rank correlation coefficient is given by 52. Concurrent Deviation Method In this method, correlation is calculated between direction of deviations and not their magnitudes. Steps in the Calculation of Concurrent Deviation • Find out the direction of change of x-variable. When a successive figure in the series increase direction is marked as + and when a successive figure in the series decrease direction of change is marked as -. It is denoted as dx. • Find out the change in direction of y-variable. It is denoted as dy. • Multiply dx and dy and determine the value of C. C is the number of positive products of dxdy (- X - or + X +). • 53. The value of Co-Efficient of Correlation always lies between +1 and –1. It can be interpreted in the following ways. • If the value of Co-Efficient of Correlation r is 1 it is interpreted as perfect positive correlation. • If the value of Co-Efficient of Correlation r is –1, it is interpreted as perfect negative correlation. • If the value of Co-Efficient of Correlation r is 0 < r < 0.5, it is interpreted as poor positive correlation. • If the value of Co-Efficient of Correlation r is 0.5 < r < 1, it is interpreted as good positive correlation. • If the value of Co-Efficient of Correlation r is 0 > r > -0.5, it is interpreted as poor negative correlation. • If the value of Co-Efficient of Correlation r is –0.5 > r > -1, it is interpreted as good negative correlation. • If the value of Co-Efficient of Correlation r is 0, it is interpreted as zero correlation.
