Justin is recording the percentages he earned on each quiz in his math class. Here are

\newline

81,92,78,93,81,76,90

\newline

Find the range of the data set.

Identify Range Extremes: Identify the highest and lowest percentages in the data set to calculate the range. $\newline$ The highest percentage is $93$ and the lowest percentage is $76$ .
Calculate Range: Calculate the range by subtracting the lowest percentage from the highest percentage. $\newline$ Range = Highest percentage - Lowest percentage = $93 - 76 = 17$
Verify Subtraction: Verify that the subtraction was done correctly and that no numbers were omitted or added incorrectly. $93 - 76 = 17$ , which is correct.
