The chi-square calculator computes the χ2 parameters for an table of data.
INSTRUCTIONS: Enter the following:
chi-square (χ2): The calculator returns:
Click on the text field for parameter OB. You can either upload a CSV file or manually enter rows of data where each observation is separated by a comma as follows:
`"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
