Question

Quizplus · Accepted Answer

A scatter plot with widely scattered data points around a line that slopes down to the right indicates a weak negative correlation, meaning there is a negative relationship between the two variables but it is not very strong. The closest value to this type of correlation is .40, which is option C. The other options, 80 and 40, are too high to be good estimates of correlation and .80 indicates a strong positive correlation, which is not what the scatter plot shows.
