Question

Use the data for the books each class donated for a book drive and find the upper quartile. 28 15 40 45 27 19 50 36 42 37 21 25

A.35
B.18
C.41
D.23

Answer 1

41

Explanation:

when you find the median you split the numbers in half from the upper to lower parts of the data. then you find the median of the upper part and that is the upper quartile.

median: 32

32, 36, 37, 40, 42, 45, 50

add 40+42 then divide by 2 and you get 41

hopefully this helps
