Question

How to find the mean median and mode in a histogram?

Answer 1

Answer:

For each histogram bar, we start by multiplying the central x-value to the corresponding bar height. Each of these products corresponds to the sum of all values falling within each bar. Summing all products gives us the total sum of all values, and dividing it by the number of observations yields the mean.

Mode = peak of dataset so, whichever bar of histogram is tallest, the mid point of that class is mode.

Median = Middle of data-set. Suppose the data size is n. If n is odd, median = mid point of the class that contains the n+12 th entry.
