Lesson 6: 1.6 Measuring Center
Duration of Days: 3
Lesson Objective
Find and interpret the median of a distribution of quantitative data.
Calculate the mean of a distribution of quantitative data.
Compare the mean and median of a distribution, and choose the more appropriate measure of center in a given setting.
What does the mean represent in the context of the data?
What does the median represent in the context of the data?
How does the mean compare to other measures of center, such as the median?

Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
Students will be able to calculate and interpret the mean and median of a data set and compare the mean and median to determine the most appropriate measure of center for a given data set.

For advanced students: Provide more complex data sets and challenge them to analyze the data in greater depth.
For struggling students: Provide additional support and simplified data sets.
