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 |
