Measures of Variability

Measures of variability provide crucial insights into the dispersion or spread of data points within a dataset. They offer a quantitative understanding of how much individual data points deviate from the central tendency, such as the mean or median. Common measures of variability include the range, which encapsulates the difference between the maximum and minimum values, and more sophisticated measures like the standard deviation and variance, which provide a deeper understanding of the distribution's shape and the extent of deviation from the mean. These measures are fundamental tools in statistical analysis, aiding in the interpretation and comparison of data sets across various fields.
