For symmetric data distributions, what measure of center would be the best average for the data?

• Mean

• Median

Find the median: 7, 1, 9, 5, 3

• 2

• 5

• 7

• 4

What is the shape of the distribution?

• Skewed Left

• Skewed Right

• Symmetric

• Uniform

For skewed data distributions, which measure of center would be the best average?

If the balance point for a set of data is 12, what 2 values can be added to the data to keep the balance point the same?

• 6 and 19

• 8 and 14

• 2 and 15

• 5 and 19

• 17, 14, 14, 8, 12

• 17, 14, 14, 12, 8

• 8, 12, 14, 14, 17

• 14, 8, 12, 17, 14
