CRP Fundamentals & Core Principles 2

Question 1

Which type of research design is BEST suited when a researcher wants to establish a cause-and-effect relationship between two variables?

Accepted Answer

Experimental design

Answer

Experimental designs use random assignment and controlled manipulation to establish causal relationships between variables.

Question 2

In a double-blind study, who is unaware of the treatment assignment?

Accepted Answer

Both participants and researchers

Answer

In a double-blind study, both participants and the researchers assessing outcomes are unaware of treatment assignments to minimize bias.

Question 3

A researcher measures annual income in exact dollar amounts. This variable is measured at which scale?

Accepted Answer

Ratio

Answer

Ratio scale has a true zero point (no income = $0) and allows meaningful ratios, making income a ratio-level variable.

Question 4

What is the PRIMARY purpose of a literature review in the research process?

Accepted Answer

To identify gaps and build a theoretical foundation

Answer

A literature review synthesizes existing knowledge, identifies research gaps, and provides the theoretical framework for new research.

Question 5

When researchers generalize findings from a sample to a broader population, they are engaging in which type of reasoning?

Accepted Answer

Inductive reasoning

Answer

Inductive reasoning moves from specific observations (sample) to broader generalizations (population).
