Question

Use the image to answer the question.

A number line with arrows on both sides extends from 86 to 90 in increments of 1. It shows an abacus-like representation with open circles equally spaced in vertical rows above the numbers. There is one open circle above 86, four open circles above 87, no circles above 88, six open circles above 89, and four open circles above 90.

Mel creates this dot plot based on a numerical dataset. Which dataset did he use to get the information for his dot plot?

86 1
87 4
88 0
89 6
90 4

Answer 1

Mel used the dataset where each number from 86 to 90 represented the number of open circles above each number on the dot plot. So, for example, the number 87 was represented by four open circles.
