Manage the modalities

Recall : The transformation Manage the modalities is possible for the scale and closed variables (unique and multiple).

You can regroup, rename, delete or arrange the modalities (for a recall, the modalities are all the possible values / responses of a variable), or create a variable for each of the modalities of the variable selected (operating mode developed below).

In the case of a multiple closed variable, you can « Create a variable containing the number of effective responses » (for example if for one question the respondent may make at maximum three choices, this new variable created will take 0, 1, 2 or 3 for values according to the number of choices made by the respondent). You can also « Create a variable from the combinations of their modalities » (for example, in the case where the respondent has selected « Home » and « Restaurant » for a question asking him "where do you mostly drink", the variable created will contain, for this observation, the modality « Home_Restaurant »).

The particular case of an arranged multiple closed question gives you the possibility to « Create one variable for each rank». (If for a question the respondent selects « Home » first  « Restaurant »  second, the assistant will create two variables which will respectively have « Home » and « Restaurant » as modalities).

Regroup the modalities

We will regroup, in our example, the images selected on the wall of images in function of their alcoholic or non-alcoholic nature.

To create a group (regroup the modalities), select the interesting modalities then click on the button  . In our example we have selected all the modalities refering to an image representing an alcoholic beverage. After selecting, the button  has therefore allowed us to regroup these modalities in the group named « Alcoholic beverages ». We have proceeded the same way for the non-alcoholic beverages and the images not allowing to know the nature (alcoholic or not) of the beverage represented.

Once all the groups are created (here three groups), click next.

Choose if you wish to modify the variable chosen by recoding it (the initial variable will be lost) or if you want to create a new variable.
Click Finish then validate and quit the assistant.

Create one variable for each of the modalities

It is possible from this assistant to create a unique closed variable for each of the modalities of the variable selected.

Two possibilities are proposed :

• The new variables created will contain « Yes » or « No» for each of the modalities chosen on the original variable. If on your original variable, you propose two modalities, for example « Always » and « Never » and the respondent selects « Always ». The two new variables which will be created in your data set will be « Always » which will have  « Yes » for value, and « Never » which will haver « No » for value.
• The new variables created will contain, in function of the modalities chosen on the original variable, either the name of the modality chosen, or a non-response. If on your original variable, you propose two modalities, for example « Always » and « Never » and the respondent selects « Always ».The two new variables which will be created in your data set will be « Always » which will have « Always » for value, and « Never » which will be in non-responses (empty field).

In the case of the creation of new variables, when you click finish, as many variables as the original one will be created as the original variable possesses modalities. If you have selected The modalities « Yes and No », the new variables created will have « Yes » or « No » for modalities. If the respondent has chosen the original variable then the new corresponding variable will take the value « Yes », in the contrary case it will take the value « No ».

If you have selected « One modality in the name of the original  modality », only the variable corresponding to the modality of the variable selected will have for modality the name of the original modality, the others will be « empty ».

Create a variable containing the number of actual responses

From this assistant, you can create a numerical variable containing the number of effective responses of the initial variable chosen (in this case, « Selected Pictures »). In the case of an empty response, you can assign as value to the new variable either a non-response (empty cell) or the numerical value 0.

In this case, it is not possible to recode the existing variable but actually to create a new variable. Choose where you wish to insert this variable (after the initial variable or at the end of the questionnaire). Click Finish to validate and quit the assistant.

Create a variable for each rank

This assistant allows to create as many new variables as the initial one possesses ranks (If the variable possesses two ranks, two variables will be created). each variable will contain the set of modalities of the original variable and will take the modality of the concerned rank for value. Click Finish to validate and quit the assistant.
