- You may have decided to collect (primary) data or use existing data – i.e., data collected by someone else.

• If the sample is relatively small, some statistical analysis can be performed manually with calculators, or with
spreadsheet application.
- However, data or mostly analyzed by computer using statistical software applications, such as R or IBM SPSS
