Section A (20 Marks)
Write short notes on any four of the following:
1. Ordinary Scale
Answer : When items are
classified according to whether they have more or less of a characteristic, the
scale used is referred to as an ordinal scale (definition of ordinal scale).
The main characteristic of the ordinal scale is that the categories have a
logical or ordered relationship to each other. These types of scale permit the
measurement of degrees of difference, but not the specific amount of
difference. This scale is very common in marketing, satisfaction and
attitudinal research. Any questions that ask the respondent to rate something
are using ordinal scales. For example,
How would you rate the service of our wait-staff?
Excellent 0 Very good 0
Good 0 Fair
2. Test of Significance
Answer : Once sample data has
been gathered through an observational study or experiment, statistical
inference allows analysts to assess evidence in favour or some claim about the
population from which the sample has been drawn. The methods of inference used
to support or reject claims based on sample data are known as tests
of significance.
Every test of significance begins
with a null hypothesis H0. H0 represents a theory that has been put forward,
either because it is believed to be true or because it is to be used as a basis
for argument, but has not been proved. For example, in a clinical trial of a
new drug, the null hypothesis might be that the new drug is no better, on
average,
3. One way ANOVAs
Answer : A One-Way Analysis of
Variance is a way to test the equality of three or more means at one time by
using variances.
Assumptions
The populations from which the
samples were obtained must be normally or approximately normally distributed.
The samples must be independent.
The variances of the populations must
be equal.
Hypotheses
4. Approaches to Report
Writing
Answer : Direct Approach
When you use the direct approach,
the main idea (such as a recommendation, conclusion, or request) comes in the
"top" of the document, followed by the evidence. This is a deductive
argument. This approach is used when your audience will be neutral or positive
about your message. In the formal report, the direct approach usually mandates
that you lead off with a summary of your key findings, conclusions, and
recommendations. This "up-front" arrangement is by far the most
popular and convenient for business reports. It saves time and makes the rest
of the report easier to follow. For those who have questions
5. Disguised- Universal
observation
Answer :
Section B (30 marks)
(Attempt any three)
1. Discuss the factors
to be taken into account before judges whether hypothesis is good or bad.
Answer : A hypothesis is a
tentative statement about the relationship between two or more variables. A
hypothesis is a specific, testable prediction about what you expect to happen
in your study. For example, a study designed to look at the relationship
between sleep deprivation and test performance might have a hypothesis that
states, "This study is designed to assess the hypothesis that sleep
deprived people will perform worse on a test than individuals who are not sleep
deprived."
Unless you are creating a study
that is exploratory in nature, your hypothesis should always explain what you
expect to happen during the course of your experiment or research.
2. Multivariate
analysis is a collection of methods for analyzing data in which a number of
observations are available for each output.
Answer :
3. Explain the various
methods to check the validity of scale used for measurement.
Answer : Construct Validity
The validity of a measurement
method is the extent to which it measures what it is supposed to measure. For
example, does an intelligence test really measure intelligence? Does a
self-esteem scale really measure self-esteem? Does whether or not someone
throws his soda can into a recycling bin indicate his level of environmental
consciousness? This overall validity of a measurement method is sometimes
referred to as its construct validity.
Evaluating Validity
There are some extremely
important points to remember about the way that psychologists evaluate the validity
of a measurement method. First
4. What are the
contents of a research proposal?
Answer : CONTENTS OF A RESEARCH REPORT
The information in the first part
of this section, Journal Articles, Books, Chapters in Books, Peer Reviewed
Published Conference Proceedings, Non-peer Reviewed Published Conference
Proceedings is filtered and extracted to formulate the Preliminary Publication
Count for the Department of Education. This is a crucial step in the subsidy
calculation process and it is of the utmost importance that this information
must be as comprehensive accurate as possible. All research publications, which
appeared in 2004, must be included, even if they are "in press".
