HR Research & Evidence-Based Practice 2

Question 1

A company wants to determine whether a new onboarding software reduces time-to-productivity. Which research design best establishes causality?

Accepted Answer

Randomized controlled experiment with a control group

Answer

A randomized controlled experiment isolates the effect of the onboarding software by comparing it to a control group, establishing causality.

Question 2

In HR analytics, what does 'p-value < 0.05' typically indicate?

Accepted Answer

There is less than a 5% probability the result occurred by chance

Answer

A p-value below 0.05 means there is less than a 5% probability that the observed result is due to random chance under the null hypothesis.

Question 3

Which data collection method is most appropriate for capturing nuanced employee sentiment about a newly deployed HRIS?

Accepted Answer

Semi-structured qualitative interviews

Answer

Semi-structured interviews allow employees to express nuanced opinions and unexpected insights that structured surveys cannot capture.

Question 4

An HR team finds that employee engagement scores correlate strongly with manager tenure. What is the appropriate conclusion?

Accepted Answer

Longer tenure and higher engagement share a statistical relationship but causation is unproven

Answer

Correlation establishes a statistical relationship but cannot confirm that one variable causes the other without additional experimental evidence.

Question 5

Which validity type assesses whether an HR assessment tool actually measures the construct it claims to measure (e.g., leadership potential)?

Accepted Answer
