Calculating Interquartile Range and Quartiles

Calculating Interquartile Range and Quartiles

Measures of spread, such as the range and interquartile range (IQR), are fundamental statistical tools used to describe the variability or dispersion within a dataset. They complement measures of central tendency, like the mean or median, by indicating how data points are distributed around these central values. Understanding spread is crucial for interpreting data accurately, as two datasets can have the same mean but vastly different levels of variability.
