Instructions

Play through this interactive game to learn about Make Observations Using Mean. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

If all measurements in a population are known, no sampling is necessary and data comparisons involve the calculated measures of center.

Use visual comparisons to make conjectures about the data.

For distributions in which the mean is the better measure of center, variation is measured in terms of how far the data values deviate from the mean. Calculate how far each value is above or below the mean, and these deviations from the mean are the first step in building a measure of variation based on spread to either side of center.

Averaging the absolute values of the deviations leads to a measure of variation that is used to describe the spread of a data distribution and in comparing distributions. This measure is called the mean absolute deviation, or MAD.

Average the absolute values of the deviations from mean to determine MAD.

Range (difference between the minimum and maximum values in a data set) and interquartile range can be used as a measure of comparative variability.

Discussion Questions

Before the Game

How is a histogram different in appearance than a dot plot? What two things are used to determine the distribution of data? How do we calculate the mean and median of a set of data? What is sampling?

After the Game

When is it necessary to use sampling to gather data and when is it unnecessary to use sampling? What is the advantage of calculating the range of a set of data? What does the mean absolute deviation (MAD) help us to determine? What do we know about a set of data with a large mean absolute deviation? Why are absolute deviations always positive numbers? Which aspects of data require us to put the data in ascending order? What is a range of the data set 10, 23, 7, 9, 14? What is the mean absolute deviation for the data set 4, 18, 15, 6, 12? What is the interquartile range of 2, 4, 12, 13, 20, 3, 4, 1, 12 ?
