U-Tab™ Tutorial - Creating New Variables Overview © 2004 Weeks Computing Services. All Rights Reserved. If the variables included in your U-Tab file are not sufficient for your requirements, i.e. you may find that being able to define three independent bases to a table is not enough to get to the segment you want to analyse, or you may want to net several responses together and create a merged code. This is when you need to create a new variable. The toolbar on the bottom left of the U-Tab window houses 3 icons for creating new variables. Click on the Icons below to view the tutorials for each function The first icon is for creating a new variable containing a Single Code. This option is most often used when you want to create a new base. The first icon is for creating a new variable containing a Single Code. This option is most often used when you want to create a new base. The second icon is for creating a new variable containing a list of Multiple Codes. This option is used when you want to create a new banner, net some codes together, or a sub-set of variables from an existing list. The second icon is for creating a new variable containing a list of Multiple Codes. This option is used when you want to create a new banner, net some codes together, or a sub-set of variables from an existing list. The third icon is the Quick Banner option, which is an easy way to create a simple banner made up from two existing variables, e.g. Age within Gender. Click to Continue…

U-Tab™ Tutorial - Creating New Variables Creating New Variables - The Multicode Variable Construction Window © 2004 Weeks Computing Services. All Rights Reserved. A multiple code variable is constructed by selecting individual codes from existing variables and combining them to form a new, complex variable. The process involves: (1) Selecting the variables that contain the codes you wish to use; (2) Selecting the appropriate codes from those variables, and (3) Defining how those codes are to be combined to create the new variable. This is all done within the multiple code variable construction screen. For example you may wish to create a variable that uses wider age bands than is contained in the existing variable. You would do this by taking the existing Age variable and combining some of the codes into a smaller number of codes. Open the multiple code variable construction dialogue box by clicking the multiple code construction icon on the main U-Tab tool bar. Your will see: The variable construction window The window used for constructing multiple code variables has four main areas: Variable titles list. This displays the index of all the variables in the project database, including any user-defined variables you may have added earlier. Variable codes. This displays the codes of any variable that has been selected and from which the codes of the new variable will be constructed. Construction area. This is used to define the way the codes for the new variable are combined. New variable list. This displays the definition of the new codes and the name you have assigned to the variable.

U-Tab™ Tutorial - Creating New Variables Creating New Variables - Explanation of Code Options © 2004 Weeks Computing Services. All Rights Reserved. Add - Adds the selected codes to the Construction Area to form codes of the new variable Net/Roll - Nets the selected codes into one new code and adds this to the Construction Area to form a code of the new variable. If the codes define a time-line, you will be given the option to "roll" codes together to form a "moving average". Condition - The selected code (single code only) will be used to define a condition (or filter) for the codes listed in the Construction Area. You can then use the drop-down combo box to select the Logical Operator (OR, AND, or NOT) you require. If the code you use to define a condition is a numeric value (e.g. actual age), you will need to specify the range that this variable needs to meet to satisfy the condition. Use the pull down menu to specify which operator (i.e. greater than, equal to etc) you wish to use.

Use the pull down menu to specify which operator (i.e. greater than, equal to etc) you wish to use. Merge - Merges selected codes with those already in the Construction Area on a one-to- one basis. The number of selected codes must equal the number of codes already in the Construction Area. If, for example, if you had a list of companies people had press advertising awareness of, you could add this to the Construction area, then Merge these with a list of companies people had television advertising awareness of. The resulting variable would then contain the combination of the two. Merge - Merges selected codes with those already in the Construction Area on a one-to- one basis.

If, for example, if you had a list of companies people had press advertising awareness of, you could add this to the Construction area, then Merge these with a list of companies people had television advertising awareness of. The resulting variable would then contain the combination of the two. Note – Logical Operators AND - Both conditions must be met. e.g. Married men must be both married AND male. OR - Either condition will satisfy. e.g. Europeans can be from France OR Germany OR Italy OR... NOT - The condition must not be met. e.g. Vegetarians are NOT meat eaters. Note that in U-Tab ORs are evaluated before ANDs, and the NOT operator is evaluated last. Click on either Merge, Add, Condition or Net/Roll button below for an explanation of that code option Close
