# Recoding

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.

Outputs

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.

The functionality is available for users of the 3KA package for individuals, and for users of the business packages for groups.
