Question

use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits.

minimum = 9, maximum = 60, 7 classes

the class width is .
(type a whole number.)

Explanation:

Calculate the range of the data

Using the Class Width Calculation knowledge point

$$ \text{Range} = \text{Maximum} - \text{Minimum} = 60 - 9 = 51 $$

Determine the class width

Using the Class Width Calculation knowledge point

$$ \text{Raw Width} = \frac{\text{Range}}{\text{Number of Classes}} = \frac{51}{7} \approx 7.2857 $$

Rounding up to the next whole number gives:

$$ \text{Class Width} = 8 $$

Answer:

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits.

minimum = 9, maximum = 60, 7 classes

The class width is <blank>8</blank>.
