It details the relationship between standard deviations, cumulative percentages, percentiles, T-scores, and stanines. By visualizing population distribution, the chart enables users to interpret standardized testing results and evaluate performance levels—ranging from extremely below average to extremely above average—relative to peers of the same age or grade level. The document serves as an essential reference for understanding normal distribution patterns, identifying skill level benchmarks, and normalizing assessment data in educational or psychological testing contexts. With clear demarcations for key statistical markers, it aids in assessing how individual scores fit within the broader context of the normal curve, facilitating precise analysis of performance
