Sample size, number of single correlations, and number of studies^a from which data were extracted.

Motive domain	Sample size	Number of single correlations	Number of studies
Overall	6151	167	56
Affiliation	4060	52	36
Achievement	5212	87	48
Power	2601	28	21

“Number of correlations” for the overall relationship is the sum of single correlations from the motive domains. A study could investigate several motives simultaneously, contributing to “sample size” and “number of studies” for more than one motive domain.

^aStudies are independent samples, not papers.
