# Best measure of central tendency

Directions:

• For each of the following data sets, select the best measure of central tendency. In a few sentences, explain why your selection is the best measure of central tendency. Then compute that measure of central tendency for the data.
• Clearly show all the mathematical steps taken to compute the measure of central tendency.
• Be sure to include an introduction and a conclusion in your assignment. A good introduction will give background on measures of central tendency, provide motivation for learning these ideas, and relate any personal experiences you have with the topic. A good conclusion will summarize your answers and provide insights learned from this assignment.
• Please remember that any written part of your assignments must follow APA standards.
