If you try to set up a custom variable on age range in business analyst using the sliders or simply typing numbers, its unclear if you are specifying a band that includes the ages of the numbers you type, or something slightly less. In other words, if you specifying 0 to 18 yrs of age, by using 0 and 18 as the brackets, the data is automatically named "less than 18 yrs of age" (implying those age 18 are excluded). Its not clear if that is a mistake in the automatic naming convention, or if the sliders are just poorly explained. Does anyone know? The documentation doesn't specify.
