# If the correlation coefficient between x and y is 0.8, what is the correlation coefficient between x – 5 and y – 3 - Mathematics and Statistics

Sum

If the correlation coefficient between x and y is 0.8, what is the correlation coefficient between x – 5 and y – 3

#### Solution

Correlation coefficient remains unaffected by the change of origin and scale.

i.e., if "u"_"i" = ("x"_"i" - "a")/"h" and "v"_"i" = ("y"_"i" - "b")/"k", then Corr (u, v) = ± Corr (x, y), according to the same or opposite signs of h and k.

Corr (x – 5, y – 3) = Corr (x, y) = 0.8
