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|
