CWP Research Methods and Evidence 2

Question 1

Which statistical measure best describes the spread of data around the mean in a wellness intervention study?

Accepted Answer

Standard deviation

Answer

Standard deviation quantifies how much individual data points deviate from the mean, making it the most informative measure of variability in wellness research.

Question 2

A wellness researcher wants to establish that a mindfulness program CAUSES reduced stress rather than simply correlating with it. Which design is most appropriate?

Accepted Answer

Randomized controlled trial

Answer

A randomized controlled trial with random assignment and a control group is the gold standard for establishing causality in intervention research.

Question 3

What does a p-value of 0.03 indicate in wellness research?

Accepted Answer

There is a 3% probability the result occurred by chance if the null hypothesis is true

Answer

A p-value of 0.03 means there is a 3% probability of observing results at least this extreme if the null hypothesis (no effect) were true.

Question 4

In a wellness study, 'blinding' participants to whether they receive the active intervention primarily prevents which bias?

Accepted Answer

Placebo effect and response bias

Answer

Blinding prevents participants from changing their behavior or self-reporting based on knowledge of their group assignment, controlling for the placebo effect and response bias.

Question 5

Which type of validity refers to how well a wellness questionnaire actually measures the construct it claims to measure?

Accepted Answer

Construct validity

Answer

Construct validity confirms that an instrument truly measures the theoretical construct of interest, such as subjective well-being or resilience.
