                                                                                    Show work…..

1. Minimum                 ________

2. Maximum                 ________

3. Mode                       ________

4. Median                    ________

5. Mean                        ________

6. Standard Deviation              _______

7. Variance                              _______

8. Mean Deviation                   _______

9. Coefficient of Variation       _______

            (try this with various data sets and be prepared for a weighted example as well)

___________________________________________

Be Ready to Compare and contrast

10. Precision vs. Accuracy,

11. Discrete variables vs. Continuous variables,

12. Quantitative data vs. Qualitative data

13. Nominal data vs. Ordinal data

14. Skewness and Kurtosis

15. Equal interval classification vs. Natural breaks classification

16. Absolute dispersion vs. Relative dispersion

17. Observations vs. Variables

Be ready to define

Standard distance, Absolute dispersion, quantiles, the least squares property of the mean, the coefficient of variation, sample, data, or any other Key Term from the ends of the chapters in the text.

Example short answers

18. Using examples, explain the difference between explicitly spatial statistics and implicitly spatial statistics.

19. You have a data set that is positively skewed.  Using a diagram, show where the mean, median and mode would be.  In your words, what does this positive skewness tell you about the distribution of scores?

20. Using an original example, explain the ecological fallacy.

Graph questions.

Set up a graph like the one below showing 5-10 points with X and Y coordinates, then calculate and plot.
