CSCS Data Analysis & Reporting 5

Question 1

A CSCS practitioner uses linear regression to predict 1RM bench press from a 3RM test. The R² value is 0.91. What does this indicate?

Accepted Answer

91% of variance in 1RM is explained by the 3RM test score

Answer

R² (coefficient of determination) indicates the proportion of variance in the dependent variable (1RM) explained by the predictor variable (3RM test).

Question 2

When conducting athlete performance reviews, which data reporting practice best supports athlete buy-in and long-term development?

Accepted Answer

Providing individualized comparisons to personal bests alongside group norms

Answer

Combining individual progress tracking with normative context gives athletes both personal motivation and a sense of where they stand, supporting engagement and development.

Question 3

A team's average vertical jump improves from 24 to 26 inches after a 10-week program. The standard deviation is 3 inches. What is the effect size (Cohen's d)?

Accepted Answer

0.67

Answer

Cohen's d = (26-24)/3 = 2/3 ≈ 0.67, which represents a medium-to-large effect size for the training intervention.

Question 4

In a CSCS testing environment, 'ecological validity' refers to:

Accepted Answer

Whether the test results generalize to actual sport performance conditions

Answer

Ecological validity describes how well laboratory or controlled test conditions reflect real-world sport performance contexts.

Question 5

A strength coach is analyzing training logs and notices an athlete's weekly load data are not normally distributed. Which non-parametric test should replace the paired t-test for pre/post comparison?

Accepted Answer

Wilcoxon signed-rank test

Answer

The Wilcoxon signed-rank test is the non-parametric alternative to the paired t-test, used when data violate normality assumptions.
