The advantage of reporting effect size is that it:

A) tells us what the sample as a whole, or on the average, is like.
B) can be represented on a pie chart.
C) is more accurate than the correlation coefficient.
D) provides a scale of values that is consistent across all types of studies.

Effect Size

A quantitative measure of the magnitude of a phenomenon, used to indicate the size of an effect or difference.

Sample

A subset of individuals from a larger population used to conduct research or test theories.

Correlation Coefficient

A statistical measure that indicates the extent to which two or more variables fluctuate together. A higher absolute value suggests a stronger relationship.
