Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

1. Explain the concept of Research Design. Describe some important research design for research study.

Answer: A research design is the "blue print" of the study. The design of a study defines the study type (descriptive, correlational, semi-experimental, experimental, review, meta-analytic) and sub-type (e.g., descriptive-longitudinal case study), research question, hypotheses, independent and dependent variables, experimental design, and, if applicable, data collection methods and a statistical analysis plan. Research design is the framework that has been created to seek answers to research questions.

Design types and sub-types

There are many ways to classify research designs, but sometimes the distinction is artificial and other times different designs are combined. Nonetheless,

2. Examine the merits & limitations of the observation method for collecting data. Illustrate your answer with suitable examples.

Answer: Observation is a fundamental way of finding out about the world around us. As human beings, we are very well equipped to pick up detailed information about our environment through our senses. However, as a method of data collection for research purposes, observation is more than just looking or listening. Research, simply defined, is “systematic enquiry made public” (Stenhouse, 1975). Firstly, in order to become systematic, observation must in some way be selective. We are constantly bombarded by huge amounts of sensory information. Human beings are good at selectively attending to what is perceived as most useful to us.

3. What is the meaning of measurement in research? What difference does it make whether we measure in terms of a nominal, ordinal, interval or ratio scale?

Answer: Measurement is at the core of doing research. Measurement is the assignment of numbers to things. In almost all research, everything has to be reduced to numbers eventually. Precision and exactness in measurement are vitally important. The measures are what are actually used to test the hypotheses. A researcher needs good measures for both independent and dependent variables.

4. Assume a research topic of your choice and give the complete format of its research report.

Answer:

Appendices

Most reports have at least one appendix section to allow you to include data, figures and calculations without breaking the flow of the main body of the report. Most scientists reading your report will not be too interested in the exact details, only the results.

The appendix, however, allows somebody interested in your results to check your research more thoroughly. Whilst it can be regarded as a 'dumping ground' for peripheral information and raw data, it should still be structured properly and referred to in

5. A chain of departmental stores opened three stores in Mumbai. The management wants to compare the sales of the three stores over a six day long promotional period. The relevant data is given below.

Store ‘A’ Sales	Store ‘B’ Sales	Store ‘C’ Sales
16 17 21 18 19 29	20 20 21 22 25 28	23 24 26 27 29 30

Use the Kruskal-Wallis test to compare the equality of mean sales in all the three stores.
