You've created your first crosstab report! Now, let's view it. We will use a very simple crosstab as an example.
Across the top of the report are a series of checkboxes for these elements:
- row percentage
- column percentage
- percentage from expected
- row total
- column total
- count
Removing the check for any of the listed elements will remove the display of that item. You might want to do so to simplify the appearance of the report. For instance, here's the report with every box checked:
Here's the same report with some of the elements removed:
Some items in the crosstab deserve special attention.
- The percentage from expected shows how far this number is from the value we would expect to see if our variables are independent of each other. It is shown if it is significant. We see above that 29% fewer males chose yellow as their favorite number than we expected.
- The p-value represents the probability that there is no relationship between how respondents have answered each question. The lower the p-value, the more confident we can be that such a relationship exists. The p-value in this report is 0.001, so we can be reasonably confident that a relationship exists.
- The T coefficient is Tschuprow's T, a measure of the strength of the relationship between the variables in the crosstab. The higher the T coefficient, the stronger the association.
This article goes into more detail about each of these items.
