Example 1: Method of study.

• Now you must select how you want to get the data for your study.
• In this case, the easiest was will probably be to survey students in particular classes, use statistics which are already available from a college, or a combination of both.
• Creating your own survey can get more data to evaluate possible alternatives, however will not be as comprehensive as using data from the college.
• If it is available, data from the college will cover your entire population, however motivation and other personal data cannot be collected.
• If time allows for a questionnaire to be given to a representative sample of the population, it is better to use your own survey.
• If you have limited time and access to the college records, it may be better to use the pre-existing data.
