    The magnitude of class interval depends on range and number of classes. The range is the difference between the highest and smallest values is the data series. A class interval is generally in the multiples of 5, 10, 15 and 20.
    Sturge’s formula to find number of classes is given below :
                 K = 1 + 3.322 log N
    Where, K = Number of classes
                 N = Total number of observations
                (log N) = Logarithm of the total number of observations
