Answer:
The number of students in the sample whose heights fall within the range defined by the cell or bin of the histogram.
Example:
Let the heights of students be represented by the sample
x = [55,62,58,70,63,57,65,59,61,56]
The maximum value is 70 and the minimum value is 55.
The range of the data is 15.
If 5 cells or bins are used for the histogram, each bin will have a range of 15/5=3.
The histogram of this data sample is shown below.
The first bin has a range of [55, 58]. Its relative frequency is 3, which means that 3 students have heights within the range [55,58] inches.
