Question

Suppose that the correlation between X and Y is ρ. For constants a, b, c, and d, what is the correlation between the random variables U=aX+b and V=cY+d? Let a and c be of "the same sign".

ρUV=?

Suppose that the correlation between \( X \) and \( Y \) is \( \rho \). For constants \( a, b, c, \) and \( d \), what is the correlation between the random variables \( U = aX + b \) and \( V = cY + d \)? Let \( a \) and \( c \) be of "the same sign".

\[
\rho_{UV} = \Box
\]

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
