Question
Create a box-and-whisker plot and comment on the skewness of a data set. Recall the following from section 3.6 of the text. Box-and-Whisker Plot shows the center, spread, and skewness of a data set. It is constructed by drawing a box and two whiskers that use the median, the first quartile, the third quartile, and the smallest and the largest values in the data set between the lower and the upper fences. Any outliers (data outside the lower and upper fences) are marked by *. Lower Fence = Q1 - 1.5 · IQR, Upper Fence = Q3 +1.5 · IQR, where IQR = Inter-quartile Range = Q3 - Q1 A skewed histogram is non-symmetric and tail on one side is longer than the tail on the other side. A skewed-to-the-right histogram has a longer tail on the right side and a skewed-to-the-left histogram has a longer tail on the left side.
