The chi-square Expected Result calculator computes the χ² 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.

The Math / Science

`"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
