UNIT ONE QUESTION & ANSWERS

PART A1. Define Research

According to Clifford Woody research comprises defining and redefining problems,

formulating hypothesis; collecting, organizing and evaluating data; making deductions and

reaching conclusions

2. What the benefits are of cross sectional design

The most important advantage of cross sectional studies is that in general they are quick and

cheap. As there is no follow up, less resources are required to run the study.

3. What is Research Problem?Problem formulation refers to translating the management problem into a research problem. It

involves stating the general problem and identifying the specific components of research

problem.

4. Differentiate dependent and independent variable.

Factoror phenomenon that is changed by the effect of an associated factor or phenomenon called

dependent variable. Factoror phenomenon that causes or influences another associated factor or

phenomenon called dependent variable.

5. Define non-directional hypothesis with and example

Non directional hypotheses postulate relationship but does not offer indication of the direction

of the relationship. Eg., Education of the respondent does not have an influence on the

importance given to the information source.

6. Differentiate basic and applied research

Basic Research: Research directed toward the increase of knowledge, the primary aim being a

greater knowledge or understanding of the subject under study.

Applied Research: It is also known as decisional research, use existing knowledge as an aidto the solution of some given problem or set of problems.

Basic Research:

7. What is experimental research and experimental research design?

Exp Research: An attempt by the researcher to maintain control over all factors that may

affect the result of an experiment.

Exp Res Design: A blueprint of the procedure that enables the researcher to test his

hypothesis by reaching valid conclusions about relationships between independent and

dependent variables. It refers to the conceptual framework within which the experiment is

conducted.

8. What is exploratory design and causal design?

2/3

Exploratory research is a form ofresearch conducted for a problem that has not been clearly

defined. Exploratory research helps determine the best research design, data collection method and

selection of subjects

A causal relationship is when one variable causes a change in another variable. These types of

relationships are investigated by experimental research in order to determine if changes in one

variable actually result in changes in another variable.

9. Define treatment with an example.

In experiments, a treatment is something that researchers administer to experimantal units . For

example, a corn field is divided into four, each part is 'treated' with a different fertiliser to see

which produces the most corn; a teacher practices different teaching methods on different

groups in her class to see which yields the best results; a doctor treats a patient with a skin

condition with different creams to see which is most effective.

10. Define quantitative research.

Quantitative research is based on the measurement of quantity or amount. It is applicable to

phenomena that can be expressed in terms of quantity.

11. What are the benefits of descriptive study?

12. What is Research design?

A research design is the specification of methods and procedures for acquiring the

information needed to structure or to solve problems. In other words the researcher should

consider (1) the design technique, (2) the type of data, (3) the sampling methodology and

procedures, (4) the schedule and the budget.

13. Give a frame work for the types of research

14. Define hypothesis and its type.A hypothesis can be defined as a logically conjectured relationship between two or more

variables expressed in the form of a testable statement. Types: 1.Working hypothesis

(directional and non directional); Statistical hypothesis (Null and Alternate Hypothesis)

15. What is longitudinal research?

16. List the characteristics of good research design

17. Give example for symptoms and problems.

18. What is business research?

Business research is an organized, systematic, data-based, critical, objective, scientific inquiry

or investigation into a specific problem undertaken with the purpose of finding solutions to it.

19. What is directional hypothesis? Give example

The hypothesis which indicates the type or direction of relationship between variables is

called as directional hypothesis. In specifying the relationship between variables the terms

such as positive, negative, more than, less than and the like are used in these hypotheses.

Eg., High income consumers spend more on consumer durables.

20. Define qualitative research

3/3

It is concerned with qualitative phenomenon (i.e.) phenomena relating to or involving quality

or kind. This type of research aims at discovering the underlying motives and desires, using in

depth interviews for the purpose.

21. What is confounding variable?

PART B

1. How does one frame the research objectives? and list the characteristics of hypothesis

2. Explain exploratory research design and tools used in this research design

3. Explain the components of Research Design

4. Explain the purpose of causal research design

5. What are the characteristics of good research?

6. Discuss with examples the Pre-Experimental research designs.

7. Examine the various types of research and their relative merits and demerits

8. Describe with an example the development of hypothesis and testing of hypothesis

with a flow diagram9. Discuss the steps involved in research process

10. Explain with examples the principles of local control and Randomization

11. Discuss with example the Solomon four group designs with example

12. Explain in detail the applications of business research.

13. Difference between descriptive, exploratory and Experimental designs.
