Question

donna is recording the percentages she earned on eac
78, 80, 86, 82, 78, 67, 81
find the range of the data set.

Explanation:

Step1: Identify max and min values

First, find the maximum and minimum values in the data set. The data set is \(78, 80, 86, 82, 78, 67, 81\). The maximum value is \(86\) and the minimum value is \(67\).

Step2: Calculate the range

The formula for the range of a data set is \( \text{Range} = \text{Maximum value} - \text{Minimum value} \). Substituting the values we found, we get \( 86 - 67 = 19 \).

Answer:

The range of the data set is \(19\).
