Minitab v13 - Nonparametric Statistics

The Minitab Project 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: C1, C2

Expected counts are printed below observed counts

            C1       C2     Total
    1       26        6        32
         18.59    13.41

    2       17       25        42
         24.41    17.59

Total       43       31        74

Chi-Sq = 2.949 + 4.091 + 2.247 + 3.117 = 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 "Classification variables:", then choose "Row percents" (or column). Make sure "counts" is unchecked since checking "Chi-square analysis" will give us the counts anyway. Since it is also helpful to see the expected cell frequencies, choose the radio button that says "Above and expected count". The fields of the dialogs from the "Summaries..." and "Options..." buttons should be blank. Pressing "OK" will give the following output:

Tabulated Statistics: CatCode, FreqCode

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