Factor Analysis

Factor Analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors.

Single Trait

Refers to focusing on one characteristic feature of an individual or system for study or analysis.

Normal Curve

A symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean (about 68 percent fall within one standard deviation of it) and fewer and fewer near the extremes. Also called a normal distribution.

Standardization

Defining uniform testing procedures and meaningful scores by comparison with the performance of a pretested group.
