Module 2 Lesson 6

In this module you will review measures of central tendency

Module 2 - Lesson 6

There are four measures of central tendency:

• Mean - The average number
• Add all of the numbers and divide by the amount
• Mode - The number that occurs the most
• Median - The number in the middle
• If there are two numbers in the middle find the average
• Range - The distance from the smallest value to the biggest
• Subtract the smallest number from the largest

Lesson 6 - Measures of Central Tendency

Different types data displays:
