As a general rule, if the sample is large, the difference between the groups is large, and the range of scores within a group is small, then:

A) the results are likely to be socially meaningful.
B) the results are likely to be statistically significant.
C) the results are likely due to chance.
D) this is a triple-masked study.

Statistically Significant

A mathematical measure that indicates that the likelihood of a certain finding or result occurring by chance is highly unlikely.

Sample Size

The number of participants or observations included in a study, which impacts the study's ability to detect effects and generalize findings.

Range of Scores

The difference between the highest and lowest values in a set of numerical data, indicating the spread or dispersion of the scores.
