The Type of Number and Central Tendency

Types of data reminder: nominal, ordinal, interval, or rational.

For Questions 1, 2, and 3 using values from Gender:

1. What type of data does Gender represent?
2. What does the mean Gender of 1.4 tell us?
3. What would be the appropriate measure of central tendency for Gender?

For Questions 4, 5, and 6 using values from Fitness Score:

4. What type of data does Fitness Score represent?

5. What is the mean, median, and mode of this dataset?

6. What is the range of this data set? How is it calculated?

For Questions 7, 8, 9, and 10 using values from Weight:

7. What type of data does Weight represent?

8. What is the mean, median and mode of this dataset?

9. What is the range of the dataset? How is this determined?

10. What is the standard deviation (use sample stddev)? What does this number tell you?
