Definitions:

Statistically Significant

A statistical judgment indicating that observed data are unlikely to occur by chance, suggesting a meaningful relationship or effect.

p < .05

Represents a statistical measure indicating that the probability of the observed data occurring by chance is less than 5%, commonly used in hypothesis testing to suggest a significant effect or difference.

Correlation

A numerical indicator showing the degree to which two variables move in relation, without suggesting a cause-and-effect relationship.

p < .05

Refers to a statistical threshold indicating that the likelihood of the observed data occurring by chance is less than 5%, commonly used to infer significance in research findings.
