1. State four properties of the mean and illustrate each with an example.

2. Under what condition might you prefer to use the median rather than the mean as the best measure of central tendency? Explain why.

3. Why is the mode not used very much as a measure of central tendency?

4. The overall mean is a weighted mean. Is this statement correct? Explain.

5. Discuss the relationship between the mean and median for distributions that are symmetrical and skewed.

6. Why is the range not as useful a measure of dispersion as the standard deviation?

7. The standard deviation is a relative measure of average dispersion. Is this statement correct?

Explain
