Understanding normal distributions is crucial in psychological statistics for analyzing behavioral and psychological data. These symmetrical, bell-shaped curves represent how variables like intelligence and personality traits are distributed across a population. The mean, median, and mode coincide at the highest frequency of scores, indicating most individuals score near the average. Skewed distributions, which deviate from this symmetry, also provide significant insights into psychological assessments.
