What is the value represented by the letter D on the box plot of data?
anyanavicka [17]
Hello!

The letter D is in the place for the upper quartile

To find this you have to find the median of the data

List the numbers from least to greatest

12, 18, 34, 55, 59, 68, 80, 80

The medians are 55 and 59

To get the median we take the average of these numbers

55 + 59 = 114

114 / 2 = 57

The median is 57

To find the upper quartile you find the median of the numbers higher than 57

List the numbers that are higher than 57 in the data

59, 68, 80, 80

Take the average of 68 and 80

68 + 80 = 148

148/2 = 74

The answer is 74

Hope this helps!
