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
Look up your test statistic.
There will be a corresponding "$\displaystyle \chi_{p}^2$" 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.
