Supplied Quarter Z Raw Score Calculator
Supplied Quarter Z Raw Score Calculator — Quarter-step z input represented explicitly as a whole count of quarters; no normal distribution assumption.
Quarter-step z input represented explicitly as a whole count of quarters; no normal distribution assumption. Calculations use finite-precision arithmetic.
Accepted inputs: MEAN value: -1,000 to 1,000 number; SD value: 1 to 1,000 number; QUARTERS value: -40 to 40 number.
How the calculation works
Convert signed quarter-standard-deviation count to z by dividing by four; raw value = mean + z*sd.
Worked example
With mean value 10 number, sd value 2 number, quarters value 4 number, result is 12 number.
Assumptions and limits
Quarter-step z input represented explicitly as a whole count of quarters; no normal distribution assumption. Calculations use finite-precision arithmetic.
