Can Sturgess's Rule be used to determine class interval?

Sturges's Rule can be used to determine the number of class intervals for a frequency distribution by using the formula ( k = 1 + 3.322 \log(n) ), where ( n ) is the number of data points. While it helps in establishing the number of classes, it does not directly determine the class interval size. Instead, once the number of classes is established, the range of the data can be divided by the number of classes to find the class interval. Thus, Sturges's Rule is a useful guideline for class interval selection in data analysis.
