The coefficient of determination, r2, indicates the statistical relationship between two variables. Frequently, if there is a high correlation between two variables, we can safely assume that one causes the other. But this is not always the case—sometimes the correlation is spurious, meaning invalid and misleading. Researchers found that from 1931 to 1971 there was […]
Find and state the value of r2, the coefficient of determination, and r, the correlation coefficient. Discuss your findings in a few sentences.
Instructions For this assignment, collect data exhibiting a relatively linear trend, find the line of best fit, plot the data and the line, interpret the slope, and use the linear equation to make a prediction. Also, find r2 (coefficient of determination) and r (correlation coefficient). Discuss your findings. Your topic may be that is related […]
