 Applying Correlation Coefficients - Educational Attainment and Unemployment
 Activity Description
 hm7_160

		Students will use state and regional unemployment data for various education levels to create scatter plots and calculate correlation coefficients. Students will then compare scatter plots with different strengths of linear relationships and will determine the impact of any influential points on the correlation coefficient.
 Suggested Grade Level
 9-12
 Approximate Time Required
 120 minutes
 Learning Objectives
 Students will be able to make scatter plots of data.
Students will be able to calculate correlation coefficients using technology and by hand.
Students will be able to assess the strength of a linear relationship using correlation coefficients.
Students will be able to determine the impact of an influential point on the correlation coefficient.
