Question

Create a histogram using a technology tool. Then complete the statement.

Student Test Scores: {85, 90, 88, 92, 87, 85, 91, 89, 93, 88, 90, 85, 92, 91, 89, 86, 88, 87, 89, 90}
. Begin the histogram at 84, and create a bin size width of 2.(1 point)
The range of scores shown on this histogram is
.

Answer 1

Histogram (bins start at 84, width = 2):

84–86 | *** (3)
86–88 | *** (3)
88–90 | ****** (6)
90–92 | ***** (5)
92–94 | *** (3)

The range of scores shown on this histogram is 10 (from 84 to 94).

(For reference: the actual data range = max − min = 93 − 85 = 8.)
