65 72 68 64 60 55 73 71 52 63 61 65 74 69 67 74 50 44 75 67 62 66 80 64 construct a boxplot of the data.

Explanation:

Step1: Sort the data

44, 50, 52, 55, 60, 61, 62, 63, 64, 64, 65, 65, 65, 66, 67, 67, 68, 69, 71, 72, 73, 74, 74, 75, 80

Step2: Find quartiles

Q1 = 60, Q2 = 65, Q3 = 71

Step3: Determine min and max

Min = 44, Max = 80

Answer:

To construct box - plot: draw a box from Q1 to Q3 with a line at Q2, whiskers from box to Min and Max.
