A data set has 1000 entries ranging from 1 to 100. The data is to be divided into 10 classes for a frequency distribution table. What is the class width?

Step 1 ：Step 1: Calculate the range of the data using the formula \( Range = Maximum\ Value - Minimum\ Value \). In this case, the range is \( 100 - 1 = 99 \)

Step 2 ：Step 2: Determine the number of classes. In this case, the number of classes is 10

Step 3 ：Step 3: Calculate the class width using the formula \( Class\ Width = \frac{Range}{Number\ of\ classes} \). Substituting the given values, we get \( Class\ Width = \frac{99}{10} \)
