How to use this table

Find the row closest to your value 1 and read across to the weighted sum. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Weighted Sum Calculator for a precise answer.

Need a value that is not in the table? — the Weighted Sum Calculator does it instantly, for free, with the formula and a worked example built in.
