Question

In order to answer the question, "If total rainfall turns out to be 12.7 inches next growing season, how many bushels of corn per acre can I expect to harvest?", what kind of statistical analysis would you perform?

a.

test of hypothesis

b.

calculate a confidence interval

c.

perform a linear regression

d.

calculate a correlation coefficient

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
