7 For the data from the 1977 Stat and Biom 200 class for eye

7. For the data from the 1977 Stat. and Biom 200 class for eye color, construct: a. pie graph b- horizontal bar graph c. vertical bar graph d. a frequency table with the relative frequency of each eye color Which of the box plots on the graph has a large positive skeW? Which has a large negative skew??

Solution

boxplot A is symmetric (no skew)
boxplot B is positive skew since most of the data is concentrated on the bottom (median < mean)
boxplot C is negative skew since most of the data is concentrated on the top (median > mean)
