By the end of the session, you will be able to:

• Identify and define levels of measurement and measures of central tendency;
• Describe situations in which different levels of measurement and measures of central tendency are useful and appropriate; and
• Calculate frequency, percentage, range, measures of central tendency and be able to critique and justify their use for the exercise problems.
