How do you calculate the percentage of data within a specific range in a histogram?

Back

To calculate the percentage, divide the frequency of the specific range by the total number of data points and multiply by 100.

What does it mean if a histogram is skewed to the right?

Back

A right-skewed histogram indicates that most data points are concentrated on the left, with fewer high values stretching the tail to the right.
