Hints on commands
- Chi-square. If your data is stacked so that each line of data is a separate observation, use the Cross Tabulation and Chi Square command. You'll need to ask for the chi-square analysis by clicking on the box labeled "chi-square analysis" and asking for the appropriate calculations. Usually, you can just check the top box, "Chi-Square Analysis."
If your data is in table form, so you have summary data for each cell in the two-way table, use Chi-square analysis (two-way table in worksheet). This assumes that you have columns that represent one of the variables and rows that represent the other variable.
