Enter job values, review the estimate, then use the decision hints before ordering or quoting.
mean = (value1 + value2 + value3 + value4) / 4Add the four values together and divide by four.
This page fixes the input count at four for a quick average workflow.
Next: geometric mean of four values.
Next: harmonic mean of four values.
When you need quick formula verification before copying a result into notes around root mean square.
Keep more precision when the output will feed another formula, drawing, coordinate step, or comparison rather than being rounded once and left alone.
