Bea, a student:

From a histogram only, can you find the frequency per each increment of an interval?

Hi Bea,

A histogram is actually a graph of tabulated frequencies. Along the horizontal axis is the intervals and along the vertical axis is the frequencies.

For example: In the above histogram, the interval of 90-120 has a frequency of 25.

Hope this helps,
