`ER = (CT*RT)/(SS)`

Enter a value for all fields

The** chi-square Expected Result **calculator computes the χ^{2} expected result based on the number of samples and the row and column totals.

**INSTRUCTIONS**: Enter the following:

- (
**CT**) Column Total - (
**RT**) Row Total - (
**SS**) Sample Size

**chi-square Degrees of Freedom (DF):** The calculator degrees of freedom as an integer.

- Chi-square for a 3x2
- Chi-square for a 3x3
- Chi-square for a 4x3
- Chi-square Degrees of Freedom
- Chi-square Expected Result
- Stats Calculator

`"Expected Result" = ("Column Total" * "Row Total")/"Sample Size"`

`χ2 = sum(O^2/E) - sum(O)`

`"Degrees of Freedom" = (R-1)*(C-1)` if R≠1, then DF = C-1
