## Practice Finding the Mean, Median, & Mode for a Group of Numbers

Instructions:

Answer 7/10 questions correctly to pass.

Problem:

Correct! Not Correct! Finding the Mean (Average):

1. Find the sum of all numbers in the group
2. Divide the sum by the number (quantity) of numbers in the group

Finding the Median of a Group of Numbers:

1. Arrange the numbers from least to greatest
2. If the number (quantity) of numbers in the group (n) is:
• odd » the median is the middle number
• position (n + 1)/2
• even » the median is the average of the two middle numbers
• Find the average of the numbers in positions (n + 1)/2 ± 1/2

Finding the Mode:

1. It is helpful to arrange the numbers from least to greatest
2. It is helpful to create a table to organize each number and its frequency
3. The mode is the number or numbers that occur most often
