Basic Options tab

Binning Style

Select whether to perform an Equal-Range or Equal Population binning.

Null value bin

Specifies how to handle empty bin fields. These represent unknown values due to missing data.

Highest—Assigns null values to the highest bin
Lowest—Assigns null values to the lowest bin.
The lowest bin is always bin 1.

Target internal bins

Specifies the number of bins to fill between the end bins.

If you are performing equal-range binning, you may select this type of processing or Bin width, but not both. If you are performing equal-population binning, you may only perform internal-bin processing.

Bin width

Choose this option to perform equal-range binning.

If you are performing equal-range binning and want to select this type of processing rather than internal-bin processing, click Bin width and enter the number of units you want in each bin.
