The Weight Value column should be entered with the value of the variable to which the weight factor will be applied.  In combination, the Weight Name and Weight Value should be unique.

If My weight 1 is applied, when the value “Perth” is encountered in the City/Suburb field it will be given a weight factor of 0.5.  This means that the total frequency of records with the value of “Perth” will be halved when the data is analyzed using Apply Weights in the Histogram and Sample Statistics screens.  If My weight 2 is used, the frequency of “Perth” value records will be doubled.

 

The available weights for any election are specified in the Electoral Division Tab of the Biographical Details screen.

 

 

 

As well as  checking the Radio Button for the weights to be used, the Radio Button of the associated field where the data will be collected must also be checked.
