• Delimitation

• Limitation

• Assumptions

Which is the research method that combines both a longitudinal design and a cross-sectional design?

• Convergence design

• Explanatory design

• Divergence design

• Exploratory design

A process in which multiple referents are used to draw conclusions about the existing truth is:

Given below are the three type’s psychological investigations:

(1) Field experiments,

(2) Laboratory experiments, and

(3) Ex-post facto field studies.

If the above investigations are arranged in descending order in terms of researcher’s ability to control secondary variance, the typical order would be:

• 2,1,3

• 3,1,2

• 2,3,1

• 3,2,1

The entire aggregation of cases in which a researcher is interested is called:

• Population

• Group

• Strata

• Sample

Process of selecting a portion of the population in a research study is referred as:

• Sampling bias

• Sampling error

• Sampling

• Target population

…...is the process of selecting a portion of the population to represent entire population:

• Sampling

• Forecasting

• Validity

• Reliability

The process of selecting a subset of population for a survey is called as:

• Elements

• Triangulation

• Sampling

• Random allocation

What is a subset of the population selected to participate in study?

• Validity

• Sample

• Reliability

• All of these
