Recoding is a type of transformation by which a new variable is created by changing some or all of the values in another variable. For example, a variable containing the number children that a person has may be recoded into another variable indicating whether the person does nor does not have children. The recoding is done at the Raw Data level (i.e., a new Variable is created). For example:
Respondent | Old variable | Recoded variable |
---|---|---|
1 | 0 | 0 |
2 | 1 | 1 |
3 | 3 | 1 |
4 | 2 | 1 |
5 | 0 | 0 |
6 | 0 | 0 |
7 | 1 | 1 |
8 | 1 | 1 |
9 | 7 | 1 |
10 | 0 | 0 |
See Recoding for more detailed information and use-cases.
