A Step-by-Step Approach to Using SAS® for Univariate & Multivariate Statistics, Second Edition

Data Manipulation

Data manipulation involves performing a transformation on one or more variables in the DATA step. This section discusses several types of transformations that are frequently required in social science research. These include creation of duplicate variables with new variable names, creation of new variables from existing variables, recoding reversed items, and using IF-THEN/ELSE statements as well as other related procedures.
