CPSS Applied Research Methods 3

Question 1

A CPSS practitioner compares VO2max values measured by a metabolic cart and a field test in the same athletes on the same day. This is an example of assessing which type of validity?

Accepted Answer

Concurrent validity

Answer

Concurrent validity is established when a new measure correlates with a gold-standard measure administered at the same time.

Question 2

In a crossover study design, what is the primary purpose of a washout period?

Accepted Answer

To eliminate carryover effects from the previous condition

Answer

A washout period allows the effects of the first treatment to dissipate before participants receive the next condition, preventing carryover bias.

Question 3

Which measure of central tendency is most resistant to the influence of extreme outliers?

Accepted Answer

Median

Answer

The median is resistant to outliers because it reflects the middle score rather than the arithmetic average of all scores.

Question 4

A sport scientist uses GPS data from an entire season to analyze training load patterns without manipulating any variables. This describes which research approach?

Accepted Answer

Descriptive/observational research

Answer

Descriptive or observational research examines variables as they naturally occur without researcher manipulation.

Question 5

In hypothesis testing, a Type I error occurs when:

Accepted Answer

A true null hypothesis is rejected

Answer

A Type I error (false positive) is rejecting the null hypothesis when it is actually true, controlled by the alpha level.
