Question

While performing a Chi Squared-test, a researcher obtains a two-sided p-value of 0.16. What was her Chi Squared-statistic? Show work.

Answer 1

Here we need degrees of freedom to find the test statistic value from the p-value.

Suppose degrees of freedom = df = 17

Let's use minitab:

Click on Graph >>> Probability Distribution Plot >>>Select 4th image>>>OK

So we get the following Image in which put the given information.

Then click on Shaded Area

look the following image:

Then click on OK so we get the following output

From the above output the test statistic value is either 25.71, or 9.588

Use your degrees of freedom and try to find test statistic value for the given p-value = 0.16.
