QUESTION 20

Sports scientists were interested in the effects of anxiety and experience on high board diving performance. All three variables are correlated with each other, but what correlation test could be run if you wanted to find out the degree of ‘exclusive’ variance anxiety had on diving performance without the interaction of the experience variable?

Partial correlation

Biserial correlation

Point-biserial correlation

Semi-partial correlation

Pearson’s coefficient

Spearman’s rho

Kendall’s tau

Kolmogorov–Smirnov
