In constructing a frequency distribution,the approximate class interval is computed as
A)(maximum value − minimum value)/(number of classes).
B)(maximum value − minimum value)/(sample size).
C)(minimum value − maximum value)/(sample size).
D)(maximum value)/(number of classes − sample size).

The approximate class interval is computed by dividing the range of the data (maximum value - minimum value) by the number of classes that the data is divided into. This yields an estimate of the width of each class in the frequency distribution.
