Can ‘r’ lie outside -1 and 1 range depending on the type of data?

1.	Can ‘r’ lie outside -1 and 1 range depending on the type of data?
Answer» For any type of data, correlation (r) cannot lie outside the -1 and +1 range. The minimum limit of ‘r’ is -1 and +1 range. The minimum limit of ‘r’ is -1 and the maximum limit of r is +1. As a result, r can never lie outside these two limits. Symbolically. -1 ≤ r ≥ 1 If in any exercise, ‘r’ is outside this range it indicates error in calculation.
