Q1. Explain the four types of experimental designs.

Answer. Four major design types with relevance to user research are experimental, quasi-experimental, correlation and single subject. These research designs proceed from a level of high validity and generalizability to ones with lower validity and generalizability.

Q2. Briefly explain the concepts of reliability, validity and sensitivity.

Answer. The concepts of reliability, validity and sensitivity

There are three criteria for evaluating measurements: reliability, validity and sensitivity. It may be noted that there is a relationship between reliability and sensitivity. If we want to make an item more sensitive, it may be achieved at the cost of reliability. This means to get more sensitivity, the researcher might have to compromise with reliability.

Q3. What are the advantages and disadvantages of the questionnaire method? Illustrate with suitable examples.

Answer. The advantages of questionnaires:-

1. Practical

2. Large amounts of information can be collected from a large number of people in a short period of time and in a relatively cost effective way

Q4. What is data editing? Mention its significance.

Answer. When the researcher collects the data it is in raw form and it needs to be edited, organized and analyzed. The raw data needs to be transformed into a comprehensible form of data. The first steps in this process are to edit the data. The edited data is then coded and inferences are drawn. The editing of the data is not a complex task but it requires an experienced, talented and knowledgeable person to do so.

The purpose of data editing

Q5. Differentiate between descriptive and inferential analysis of data.

Answer. Descriptive Statistics

Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Descriptive statistics do not, however, allow us to make conclusions beyond the data we have analyzed or reach conclusions regarding any hypotheses we might have made. They are simply a way to describe our data.

Q6. Explain the Structure of the Research Report. What are the guidelines for effective report writing?

Answer. Structure of the Research Report

The reporting requires a structured format and by and large, the process is standardized. As stated above, the major difference amongst the types of reports is that all the elements that make a research report would be present only in a detailed technical report. Usage of theoretical and technical jargon would be higher in the technical report and visual presentation of data would be higher in the management report.

The process of report formulation and presentation is present. As can be observed, the preliminary section includes the title page, followed by the letter of authorization, acknowledgements, executive summary
