Instructions

Play through this interactive game to learn about Factors Affecting Measures of Center. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

Determine the effect on measures of center when a single value of a data set is added, removed, or changed.
Measures of center are types of averages for a data set. They represent numbers that describe a data set. Mean, median, and mode are measures of center that are useful for describing the average for different situations.
Mean can be defined as the point on a number line where the data distribution is balanced. This requires that the sum of the distances from the mean of all the points above the mean is equal to the sum of the distances from the mean of all the data points below the mean. This is the concept of mean as the balance point.
The mean can also be found by calculating the numerical average of the data set.
The median is the middle value of a data set in ranked order. If there are an odd number of pieces of data, the median is the middle value in ranked order. If there is an even number of pieces of data, the median is the numerical average of the two middle values.
The mode is the piece of data that occurs most frequently. If no value occurs more often than any other, there is no mode. If there is more than one value that occurs most often, all these most frequently-occurring values are modes. When there are exactly two modes, the data set is bimodal.

Discussion Questions

Before the Game

How do you find the mean of a data set? How do you find the median of a data set? How do you find the mode of a data set? When you have a set of numbers that is even, how would you find the median?

After the Game

How did you know when to find the mode of the group of customers? How did you know when the mean would be the best way to divide pizza among the customers? What is a scenario when the median would be a better measure of central tendency to use than the mean? If one customer had a value that was an outlier from the other customers, what was the best solution?
