Adding a weighting factor
Several weighting schemes may be supplied with your data file. These appear in your variable index but always start with the word "Weight". To apply a weighting factor, simply drag a weight variable over to the weight area and drop it (or right-click on the Variable Index and select the 'Replace weight' menu item).
If you'd like to see the table without the weighting applied, right click the weight area and select the clear weight option. You'll notice the weight area is cleared of text and the data in the table reflects a non-weighted output.
Another useful function is the ability to "test" the weighting scheme (by right-clicking the weight area) to see if the effect of weighting your data has produced any significant difference in percentage or score (see Significance testing for more information).
