Measures of Central Tendency

Which measure of central tendency is algebraically defined?

• Mode

• Mean

• Median

• Range

True or False: The mean, median, and mode must all be equal to each other for all sample data sets.

• True

• False

True or False: The mean is the best measure of central tendency to describe symmetric data sets.

• True

• False

True or False: The mode is the best measure of central tendency for all asymmetric data sets.

• True

• False
