Weighted Mean of Two Values Calculator
weighted average. Example: A: 2 units, B: 2 units, Dimensionless weight a: 2 number, Dimensionless weight b: 2 number gives 2 units. Two observations with strictly positive dimensionless weights; not grade or investment-policy advice. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation.
Two observations with strictly positive dimensionless weights; not grade or investment-policy advice. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation. Derivation: Normalize positive supplied weights then take weighted sum.
Accepted inputs: A: -1,000,000 to 1,000,000 units; B: -1,000,000 to 1,000,000 units; Dimensionless weight a: 0.001 to 10,000 number; Dimensionless weight b: 0.001 to 10,000 number.
How the calculation works
mean = (a wa+b wb)/(wa+wb)
Worked example
With a 2 units, b 2 units, dimensionless weight a 2 number, dimensionless weight b 2 number, weighted average is 2 units.
