Mean, Median, Mode, Range, Interquartile Range Mean The ‘Mean” is the average of a set of numbers.The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set.Example: Data Set = 2, 5, 9, 7, 5, 4,...
Unlike (total)range, the interquartile range is arobust statistic, having abreakdown pointof 25%, and is thus often preferred to the total range. The IQR is used to buildbox plots, simple graphical representations of aprobability distribution. For a symmetric distribution (so the median equals ...
