Properties of Correlation and Analysis

Range: The correlation coefficient always lies between $-1$ and $+1$ , i.e., $-1 \le r \le +1$ . 2. Independent of change of origin and scale: Correlation is unaffected by adding/subtracting a constant or multiplying/dividing by a positive constant. 3. Pure number (unit-free): It has no units of...
