Section A (20 Marks)
Write short notes on any four of the following:
1.Ex-post facto research
Answer : When translated literally, ex
post facto means ‘from what is done
afterwards’. In the context of social and educational research the phrase
means ‘after the fact’ or ‘retrospectively’ and refers to those studies which
investigate possible cause-and-effect relationships by observing an existing
condition or state of affairs and searching back in time for plausible causal
factors. In effect, researchers ask themselves what factors seem to be
associated with certain occurrences, or conditions, or aspects of behaviour.
Ex post facto research,
then, is a method of teasing out possible antecedents of events that have happened
and cannot, therefore, be engineered or manipulated by the investigator. The
following example will illustrate the basic idea. Imagine a situation in which
there has been a dramatic increase in the number of fatal road accidents in a
particular locality. An expert is called in to investigate. Naturally, there is
no way in which she
2.Hypothesis Testing
Answer : Hypothesis testing is used to infer a result of a hypothesis
performed on sample data from a larger population. For example, performing a
hypothesis test on sample data in an attempt to determine the mean of a
population is the same as the mean of the sample.
A statistical hypothesis test is
a method of making decisions using data from a scientific study. In statistics,
a result is called statistically significant if it has been predicted as
unlikely to have occurred by chance alone, according to a pre-determined
threshold probability, the significance level. The phrase "test of
significance" was coined by
3.Interview
Answer : An interview is a conversation between two or more people where
questions are asked by the interviewer to elicit facts or statements from the
interviewee. Interviews are a standard part of journalism and media reporting,
but are also employed in many other situations, including qualitative research.
A conversation in which one
person (the interviewer) elicits information from another person (the subject
or interviewee). A transcript or account of such a
4.Sampling Process
Answer : STEPS
IN SAMPLING PROCESS:
It is the procedure required
right from defining a population to the actual selection of sample elements.
There are seven steps involved in this process.
Step 1: Define the population
It is the aggregate of all the
elements defined prior to selection of the sample. It is necessary to define
population in terms of
(I) elements
5.Cluster and Multi-stage Sampling
Answer :
Section B (30 marks)
(Attempt any three)
1.Discuss the important concepts of research in management.
Answer : Today’s managers have a
growing need to understand scientific findings and incorporate them into
decision making. Research always facilitates effective management. At many
government organizations research drives every aspect of major decision making.
In some organizations, research is so fundamental that management makes hardly
any significant decision without the benefit of some kind of research.
3.“There are still a number of gaps in understanding between the
researches and its users”. Elaborate this statement in the light of limitations
of research.
Answer :
4.Discuss the steps to calculate expected monetary value with the help
of examples.
Answer : How do you
quantitatively prioritize a risk? Would you prioritize the risks with the
highest probability of occurrence or the risks with the greatest monetary
impact? This is where Expected Monetary Value (EMV) comes to the rescue in
Project Risk Management.
Beginning With a Qualitative Risk Analysis...
After conducting a Qualitative
Risk Analysis, you’ll have a list of risks with a priority and urgency
assigned. By using Expected Monetary Value, you can quantify each risk to
determine whether your qualitative analysis is backed by numbers. Expected
Monetary Value is a recommended tool and technique for Quantitative Risk
Analysis in
