Thread: p value on chi squared test??

does anyone know how to get the p value of a chi squared test? I know how to get the critical value ie (c-1)(r-1) for degrees of freedom then t df, alpha but don't know how to get p value from here

Use the table...

Choose the appropriate df, scroll over to the value of your test statistic, and the p-value will be 1-the subscript on the corresponding X^2.

isnt that the test statistic or are they the same thing in chi squared tests?

Look up your test statistic.

There will be a corresponding " " at the top of the column.

Your p-value is 1-that p subscript....

Is this clear?

Example:

For test statistic = 1.32 and 1 df,

the p-value = 1-.25 = .75.

thanks really helpful!!!!
