Document Summary
Not resistant for outliers if the distribution is. If n is odd include the median in both halves. This is a measure of spread less affected by outliers. S measures the spread about the mean x. S=0 only when there is no spread/ this happens only when all observations have the same value. S, like the mean x, is not resistant. If all the numbers are the same, then the standard deviation is 0 is not resistant by outliers. The ve number summary of a set of observation consists of the minimum, the rst quartile, median, the third quartile and the maximum. These ve numbers give a quick summary of the both center and the spread of the distribution. No low outlier (because no numbers in the data set is lower than 3. 5) Boxplot q1, med, q3, uf, lf, highest number in the data set lower than uf, lowest number in the data set higher than lf.
