Question

Make a box-and-whisker plot of the data. 60,63,53,66,65,58,51,55,58,51,58,62,53,66,61,51,65,52,54,50

Answer 1

Answer:

Step-by-step explanation:

To do this by hand, first sort data (you can use wolfram to do this).

Then divide data into four parts.

50, 51, 51, 51, 52, 53, 53, 54, 55, 58, 58, 58, 60, 61, 62, 63, 65, 65, 66, 66

• Minimum = 50

Q1 = (52+53)/2 = 52.5

• Median = (58+58)/2= 58

Q3 = (62+63)/2 =  62.5

• Maximum = 66

IQR = 62.5 - 52.5 = 10

• Outlier is defined as a value x such that

x >  Q3 + 1.5*IQR  or  x < Q1 - 1.5*IQR

=> There are no outliers.
