How to Determine Bin Intervals to Create a Histogram in Excel
- select a beginning point that is lower than or equal to both the lower spec limit and the min value.
- calculate bin intervals in Excel by taking the beginning value + the bin width, + the bin width, etc.

How do you find the bin range in Excel?

- Boundaries for bins should land at whole numbers whenever possible (this makes the chart easier to read).
- Choose between 5 and 20 bins.

The bin-width is set to h=2×IQR×n−1/3. So the number of bins is (max−min)/h, where n is the number of observations, max is the maximum value and min is the minimum value.

The towers or bars of a histogram are called bins. The height of each bin shows how many values from that data fall into that range. Width of each bin is = (max value of data – min value of data) / total number of bins. The default value of the number of bins to be created in a histogram is 10.
What is a data bin?
Data binning, also called discrete binning or bucketing, is a data pre-processing technique used to reduce the effects of minor observation errors. The original data values which fall into a given small interval, a bin, are replaced by a value representative of that interval, often the central value.
