This menu performs a goodness-of-fit test between data values and a set of expected values.
Available Data
This lists data structures appropriate to the current input field. The contents will change
as you move from one field to the next. Double-click on a name to copy it to the current
input field; alternatively, you can type the name directly into the input field.
Observed Data
Table containing the observed data values. You can create a table using the Summary by Groups menu or by
clicking on the Create Table button.
Expected Frequencies
Table containing the expected frequencies. You can create a table using the Summary by Groups menu or by
clicking on the Create Table button.
Degrees of Freedom
Provides a space for you to specify the degrees of freedom. If this value is supplied then
the menu can calculate the probability value for the test.
Method
You can choose between two ways of calculating the test: Pearson uses the familiar method; the alternative, which may be more accurate, is to use maximum likelihood.
Create Table
Allows you to create a new table either from existing data or by typing in the values in a blank spreadsheet.
