Supplied Whole Range Ceiling Class Width Calculator
Supplied Whole Range Ceiling Class Width Calculator — Whole-number class width convention; equal endpoints yield zero; no implied automatic bin-edge coverage.
Whole-number class width convention; equal endpoints yield zero; no implied automatic bin-edge coverage. Calculations use finite-precision arithmetic.
Accepted inputs: LOW value: -1,000 to 1,000 number; HIGH value: -1,000 to 1,000 number; CLASSES value: 1 to 1,000 count.
How the calculation works
Divide supplied range by class count and round upward to the next whole-number width.
Worked example
With low value 1 number, high value 10 number, classes value 4 count, result is 3 number.
Assumptions and limits
Whole-number class width convention; equal endpoints yield zero; no implied automatic bin-edge coverage. Calculations use finite-precision arithmetic.
