What it calculates
The “Phi Coefficient” calculator computes φ (phi) from 4 parameters: cell a (row 1, column 1), cell b (row 1, column 2), cell c (row 2, column 1), cell d (row 2, column 2).
A core calculation for studying, engineering tasks, and checking solutions.
Example calculation
With parameters Cell a (row 1, column 1) = 30, Cell b (row 1, column 2) = 10, Cell c (row 2, column 1) = 15, Cell d (row 2, column 2) = 45 the result is 0.4924.
How to use
- Enter cell a (row 1, column 1), cell b (row 1, column 2), cell c (row 2, column 1) and cell d (row 2, column 2) — each field above is adjustable with a slider.
- φ (phi) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
