This rule works by generating a new table in the background, applying the selected weight to that table, and then copying the column of weighted numbers into the original table or visualization.
This rule can take you from a crosstab with spans...
...to a crosstab or visualization with a weight applied to a specific column span, e.g., the Under 35 span:
Requirements
- A crosstab with spans.
- A weight variable.
Note: You must apply the rule directly to the input table if you see a table icon in the Data > Data Source > Data field in the object inspector of a visualization.
You will also see a warning in the Rules section of the object inspector if you have applied a rule directly to a non-compatible visualization, and you will need to apply it to the input table instead. For example:
Method
- Select your table.
- Go to Data > Rules on the object inspector
.
- Select Plus (+) > Calculation > Apply Weight to Specified Column Span.
- Select Column span to weight.
- Select your Weight variable.
- Press OK.
Technical Details
Any significance testing results for the weighted columns are taken from the weighted table only, and no attempt is made to reconcile tests between the weighted and unweighted portions of the table. This means that the results in a column with the rule applied are highly unlikely to be comparable to any columns without the rule
