Review questions 5

  • A researcher hypothesized that the young would better on both the memory

  • and the vocabulary tests. Is there evidence to support her hypotheses?

  • 2. Is there a relation between memory and vocabulary performance?

  • 3. What VT score would you predict for a subject with a MT score of 9?

  • What restrictions would you place on the prediction?

  • 4. Should the same regression line be used to predict the vocabulary scores from

  • the memory scores for both the young and the old?

  • 5. Is the strength of the relation between MT and VT different for young and old?

  • 6. Illustrate how you might convert question #2 into a Chi-Squared question.

  • How do the answers differ and why?
