For example, for the tree height histogram that shows each height, I see that I have 2 trees that are 3 feet high and 7 trees that are 6 feet high. Step 1: Open the Data Analysis box. The screenshot below shows what their raw data look like. Without this value, the histogram would be For example, if a company is using the histogram to understand the preferences of customers across two different choices, a normal distribution would represent that majority of the customers are indifferent.

Bin numbers These numbers represent the intervals that you want the histogram tool to use for measuring the input data in the data analysis. In a left-skewed distribution, a large number of data values occur on the right side with a fewer number of data values on the left side.
