overall review score: 4.7
⭐⭐⭐⭐⭐
score is between 0 and 5
Statistical measures of spread are quantitative tools used in statistics to describe the variability or dispersion within a data set. They help analysts understand how data points are distributed around a central value, providing insights into the consistency or diversity of the data. Common measures include range, variance, standard deviation, interquartile range, and mean absolute deviation.
