Frequency distribution in psychology is a statistical method for organizing data to reveal behavioral trends and psychological phenomena. It includes categorical, grouped, and ungrouped distributions, and is visualized through tables and graphs like histograms and bar charts. Understanding relative and cumulative frequencies within these distributions is crucial for interpreting complex psychological data and enhancing research findings.
