Identify and define the three measures of central tendency.

When will the mode most likely be used as a measure of central tendency?

Compute the median for the following scores: 7, 5, 10, 5, 5

Compute the median for the following scores: 4, 1, 6, 2, 11, 4

What does a measure of central tendency indicate regarding a distribution?

What does it mean that the mean is the mathematical center of a distribution?
