Abstract: What is clean data and how do you clean it? This is an age-old question that has some pretty easy answers. There are some techniques that can be used to find invalid data values in both numeric and character data, missing values of any type and duplicate o bservations. Simple procedures and DATA steps can be used to ferret out inappropriate observations. This paper will illustrate some of the techniques used after data entry is complete and the data has to be reviewed and cleansed.
