Question

Calculate the correlation coefficient​ r, letting Row 1 represent the​ x-values and Row 2 the​ y-values. Then calculate it​ again, letting Row 2 represent the​ x-values and Row 1 the​ y-values. What effect does switching the variables have on​ r?

Row 1	12	21	33	43	60	69	80
Row 2	158	115	129	105	106	145	171

Calculate the correlation coefficient​ r, letting Row 1 represent the​ x-values and Row 2 the​ y-values.

 

r=nothing

​(Round to three decimal places as​ needed.)
