You can recode numeric and categorical values of variables in 1KA, i.e. change their values. You can access this option in the 'DATA' – 'Computations' – 'Recoding' tab.
The following recoding functions are available:
- Add – opens a window for adding variables where you want to change old values to new ones.
- Edit – opens a window for editing the recoding of a variable.
- Remove – removes or completely deletes the recoding of a variable.
- Enabled – enables or disables the recoding of a variable.
- Visible – sets the visibility of the recoded variable to respondents in the questionnaire.
Below the table, you can see a list of recoded values by variable by clicking on '+ Recent recoding'.
Recoding to the same variable:
- Recode all answers that have e.g. the values 2 and 3 to another value (e.g. 11) of the same variable,
- or define them as a missing value, e.g. 'did not answer (-1)'.
Recoding into a new variable:
- Recode the responses of the selected variable into new values, where the values of the old variable Q1 (e.g. 1 and 2) are assigned a new value (e.g. 12) in the variable Q2.
- When recoding into a new variable, the values can also be defined as a missing value.
- Similarly, you can recode categorical variables, e.g. to change Q1 with a scale of 1-5 to Q2 with a scale of 1-3. You recode the values 1 and 2 of Q1 into the value 1 of Q2; you recode the value 3 of Q1 into the value 2 of Q2; and you recode the values 4 and 5 of Q1 into the value 3 of Q2. You can also perform this transformation by calculating Q2 = 1/2 + 1/2*Q1, where Q2 will of course still have five values, but on the interval 1-3.
For each variable you have added to the recoding list, you can output the frequencies, pooled frequencies, descriptive statistics and a graph with a single click. These can then be printed or exported to PDF, Word or Excel formats.
