How do you find class boundaries in statistics?

To find class boundaries in statistics, you need to first determine the range of your data. Class boundaries are the values that separate one class from another in a frequency distribution. They are half-way between the upper limit of one class and the lower limit of the next. To calculate the class boundaries, you need to subtract 0.5 from the lower limit of the first class, and add 0.5 to the upper limit of the last class. This creates an additional two classes on either end of your distribution to account for any values that fall outside of the original range. Class boundaries are useful in statistics for ensuring that data is properly grouped and analyzed.
