How to use Minitab for Chi Squared tests.
Suppose that the Observed data is
Men
Women
Vote for Hillary
16
60
Not vote for Hillary
85
140
You can use Minitab to get the test statistic and the p-value.
1. Enter the data (not the totals) into Minitab:
2. In Minitab select
Stat BasicStatistics  Tables  Chi Square Test…
3. Select the columns that hold the table and click OK
4. In the output window you will see:
Chi-Square Test: C1, C2
Expected counts are printed below observed counts
Chi-Square contributions are printed below expected counts

Chi-Sq = 7.128, DF = 1, P-Value = 0.008
The two tables Observed and Expected are superimposed on one
another.

The Chi-Sq statistic
 

(O  E)

E
is given as 7.128

The degrees of freedom is 1

The p-value is .008--- which is very small.
