Ans: Reliability refers to the consistency of a scale. Validity refers to its accuracy. A scale can be reliable even if it is not valid. This means it is consistently inaccurate, which is a possibility. However, it is not possible for a tool to be valid if it is not reliable because it cannot be accurate if it is inconsistent.
