This Correlation Coefficient lesson plan also includes:
Your class can learn about positive and negative correlation by exploring the relationship between pairs of quantitative variables. Start with a description of the variables and hypothesize if a strong or weak correlation exists. Make specific data available and have them use scatter plots to help support their claim. Use graphing calculators to find the associated line of best fit and calculate the corresponding r-value. Have students present their work and discuss if the correlation coefficient supports their original hypothesis and if a linear regression is the best model for the data.
