    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.

    Look up your test statistic.

    There will be a corresponding " \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.
