Q1. Distinguish between descriptive and causal research studies?
Answer. Descriptive studies are designed primarily to describe what is going on or what exists. Causal
studies, which are also known as “experimental studies,” are designed to determine whether one or more
variables cause or affect the value of other variables.
As the name implies, a descriptive research is descriptive in nature and gathers statistics, which is later
carefully studied to arrive at conclusions. In fact, descriptive research often leads to formulation of
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
3. Can be carried out by the researcher or by any number of people with limited affect to its validity and
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.
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.
