CRP Assessment & Evaluation Techniques 3

Question 1

What does 'construct validity' mean in the context of a research instrument?

Accepted Answer

The instrument measures the theoretical construct it is intended to measure

Answer

Construct validity refers to how well a test or measure actually captures the underlying theoretical concept it is supposed to assess.

Question 2

In cost-benefit analysis, the 'net present value' (NPV) is used to:

Accepted Answer

Account for the time value of money when comparing future costs and benefits

Answer

NPV discounts future costs and benefits to their present value, enabling a meaningful comparison of programs with different time horizons.

Question 3

Which sampling method would be most efficient when a complete list of the target population does not exist?

Accepted Answer

Respondent-driven sampling (RDS)

Answer

Respondent-driven sampling is designed for hard-to-reach populations where no sampling frame exists, using peer referral chains.

Question 4

An evaluation that compares multiple programs or sites to identify best practices is best described as:

Accepted Answer

Cross-site evaluation

Answer

Cross-site evaluations systematically compare findings across different programs or locations to identify effective models.

Question 5

Which type of error occurs when a researcher concludes there IS a significant effect when in reality there is none?

Accepted Answer

Type I error (false positive)

Answer

A Type I error, or false positive, is the incorrect rejection of a true null hypothesis, concluding an effect exists when it does not.
