Martha is wondering whether kids her age tend to eat more vegetables on weekdays or weekend days. As part of her research, she asks the statistical question “How many servings of vegetables did my friends eat last weekend?” She collects data and organizes it into a histogram. Describe the spread of the data shown in the histogram by calculating the range. Fill in the blanks.

Answer 1

To calculate the range, Martha needs to subtract the minimum value from the maximum value of the data set.

Let's say Martha collected the following data on the number of servings of vegetables her friends ate last weekend: 2, 3, 4, 5, 2, 2, 3, 5, 6, 4.

First, let's find the minimum value: 2
Next, let's find the maximum value: 6

Now, let's calculate the range: 6 (maximum value) - 2 (minimum value) = 4

Therefore, the range of the data shown in the histogram is 4 servings.
