Choosing a Data Analysis Technique

Scenario: You would like some advice in choosing statistical techniques to analyze data acquired as part of a research project. This knowledge base simulates an interview with a human expert who will help you pick an appropriate technique for each of your research questions.

The recommended minimum confidence factor (CF) used to accept an input or derived value as a fact is shown below. Setting the CF to a lower value may produce more results (with less confidence in these results):
Minimum CF:50% 60% 70% 80% 90% 100%

If you allow "cookies" to be accepted by your Web browser, you may use the Save all button on the Why ask? screen at any time during a session to store all of the answers you have submitted up to that point. To reload the answers most recently saved (if there are any), start your interview with the following button:

When you restart an interview, the minimum confidence factor will be reset to the value it had when you saved your input.
