The approximate class width for a frequency distribution involving quantitative data can be determined using the expression range/desired number of classes. This formula helps to determine the appropriate width of each interval so that the data is organized in a meaningful way. By dividing the total range of the data by the desired number of intervals, the resulting value provides a good estimate of the width that should be used for each interval in the frequency distribution.
