The formula for correlation is similar to the formula for z score in that they both:
A) take into account sample size only.
B) take into account variability only.
C) take into account sample size and variability.
D) remove outliers from the calculations.

Question

Quizplus · Accepted Answer

The formula for correlation takes into account both sample size and variability, just like the z score formula. Both of these factors are important for accurately describing the relationship between variables or scores. Correlation helps determine the strength and direction of a relationship, while the z score helps determine how far away a score is from the mean in standard deviation units. Neither formula removes outliers from calculations.
