In order to find the ideal number of classes required to construct a histogram where there are 64 sample measurements, we will be using 2^k rule.
According to 2^k rule: 2^k >= n
where k is the number of classes.
n is the number of data points.
Applying the rule, here n = 64
Hence 6 is the ideal number of classes
