3. Which of the following would not be appropriate for giving an overview of ordinal data?

Approximately 84.7% of the variance in the width of the book is due to the variation in the number of pages in the book. 6pt

5. Which test could best be used to test the hypothesis that the average grade of students is higher than a 7 on a 10-point scale?

6. Mean and median actually are identical concepts
