Once have your data, you must ANALYZE it. There are many different ways to analyze data: some are simple and some are complex. Some involve grouping, while others involve detailed statistical analysis. The most important thing you do is to choose a method that is in harmony with the parameters you have set and with the kind of data you have collected.
Detailed instruction on data analysis is beyond the scope of this module. To learn more about analyzing data, you will need to consult another source: a teacher, a statistician, a good book on the subject, or annother tutorial.
