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.
The following item is part of this activity. The item, its data source, and instructions for viewing the source data online appear at the end of this teacher version.
Students will analyze data by creating scatter plots and calculating correlation coefficients. Then they will apply their knowledge of linear regression models to evaluate any influential points in the data distribution.
