Question

Use the image to answer the question.

An illustration shows two sets of dot plots. One is titled City A Daily High Temperature in degrees Fahrenheit, and the other is City B Daily High Temperature in degrees Fahrenheit. The plots are shown as an abacus-like representation with dots in a vertical row over each number on a number line. For City A, a number line with arrows on both ends ranges from 68 to 74 in increments of 1. There are 2 dots above 68, 1 dot above 69, 2 dots above 70, 3 dots above 71, 2 dots above 72, 2 dots above 73, and one dot above 74. For City B, a number line with arrows on both ends ranges from 79 to 85 in increments of 1. There is 1 dot above 79, 2 dots above 80, 2 dots above 81, 3 dots above 82, 2 dots above 83, 2 dots above 84, and 1 dot above 85.

The dot plots show the daily high temperatures in two cities on 13 randomly chosen days in August. Which of the following informal assessments is true about these two distributions?

Data values in both distributions have similar spread.
Data values in both distributions have similar spread.

Based on visual overlap of the distribution, all data values overlap.

Answer 1

Data values in both distributions have similar spread.

Reason: City A ranges 68–74 (range = 6) and City B ranges 79–85 (range = 6); the dot plots have similar shapes and spread but are shifted apart, so variability is similar (no outliers and no overlap).
