1. IB MATH STUDIES INTERNAL ASSESSMENT Interpretation of Results and Validity

2. 1: Interpretation of Results  There are 2 scenarios for this component.  (1) Your Chi-Square test concluded with the variables being dependent.  (2) Your Chi-Square test concluded with the variables being independent.

3. Dependent Variables  Interpretation of Results:  This result allows you to use your observed results to make claims.  What do you see in your data (observed results) that is unexpected?  What makes this unexpected result in your data important to your papers research question?  What inferences can you make about this unexpected result? Who would find it important and why?

4. Independent Variables  Interpretation of Results:  So your test did not come out the way you wanted it to. Why?  What is in your observed results that makes no sense with your research question?  Quantities of cells in your observed results that are almost equal to the same cells in your expected results are to blame for the lack of a relationship. You should be able to discuss them and explain why they turned out so close.

5. 2: Validity  Data collection errors:  Were your categories set up appropriately?  Were your variables even worth comparing?  Did you have enough surveys/data points?  Was your data appropriate for your research question?  Was your research question appropriate for the data collected?  Did you collect data from the appropriate areas? Did you need more geographical diversity?  Explain why you needed to correct these errors do not simply state the error.
