Minitab - Nonparametric Statistics

The Minitab Worksheet is available. It contains the following data:

Using
Column
N
Comments
Cell
Counts
TabC1
2
The 4 observed cell counts
in tabular form.
TabCol2
2
Raw
Data
CatCode
74
Dummy codes for categories tried
(1=3 or less, 2=4 to 6).
FreqCode 74 Dummy codes for frequency of use
(1=less than 3/week, 2=3+).

Chi Square - two variable (with observed cell counts)

Use the "Chi-Square Test..." command off of the "Stat, Tables" menu. That is:

That will take you to the following dialog box:

Type in the relevant "Columns containing the table:". The output would look like this:

Chi-square Test: TabC1, TabC2

Expected counts are printed below observed counts
Chi-Square contributions are printed below expected counts

         TabC1    TabC2     Total
    1       26        6        32
         18.59    13.41
         2.949    4.091

    2       17       25        42
         24.41    17.59

         2.247    3.117

Total       43       31        74

Chi-Sq = 12.404, DF = 1, P-Value = 0.000

Chi Square - two variable (with raw data)

Use the "Cross Tabulation..." command off of the "Stat, Tables" menu. That is:

That will take you to the following dialog box:

Type in (or double click on) the "Catagorical variables:" (one for the rows and one for the columns). Then click on the "Chi-Square..." button. You will then see this dialog box:

Check the boxes indicated and then press the "OK" button twice. You will give then see the following output:

Tabulated statistics: CatCode, FreqCode
