Q.1 Choose the alternatives given below. 14
Research hypotheses are
Formulated priort to a review of the literature
Statements of predicted relationships between variables
Stated such that they can be confirmed or refuted
b and c
Analysis of covariance is:
A statistical technique that can be used to help equate groups on specific
variables
A statistical technique that can be used to control sequencing effects
A statistical technique that substitutes for random assignment to groups
Adjusts scores on the independent variable to control for extraneous
variables
of the following formulae is used to determine how many people
to include in the original sampling.
Desired sample size/Desired sample size
Proportion likely to respond/desired sample size
Proportion likely to respond/population size
Desired sample size/Proportion likely to respond
is a general methodology for developing theory that is based on
data systematically gathered and analyzed.
Theory confirmation Grounded theory
Theory deduction All of the above
If a distribution is skewed to the left, then it is
Negatively skewed Positively skewed
Symmetrically skewed Symmetrical
Sampling in qualitative research is similar to which type of sampling in
quantitative research is

Simple random sampling Systematic sampling
Quota sampling Purposive sampling
The median is
The middle point The highest number
The average Affected by extreme scores

The standard deviation is:
The square root of the variance
A measure of variability
An approximate indicator of how numbers vary from the mean
All of the above
Hypothesis in qualitative research studies usually
Are very specific and stated prior to beginning the study
Are often generated as the data are collected, interpreted and analyzed
Are never used.
Are always stated after the research study has been completed.
10) Which of the following is NOT a common measure of central tendency?
Mode Range
Median Mean
11) Hypothesis cannot be stated in
Null and question form terms Declarative terms
General terms Directional terms
12) Mean deviation is
Average deviation Deviation of sums
Deviation of total None of these
13) When there are more variables studied it is
Partial correlation
Simple correlation
Multiple correlation and partial correlation
Spurious correlation
14) Correlation can be
Only positive
Both positive and negative
Positive, negative, partial and multiple
Simple and multiple
