Is there a difference between "is reliable" and "is valid"?

While both terms indicate quality, "is reliable" means consistent performance or results over time. "Is valid" means the information accurately reflects what it claims to measure. A measurement can be reliable without being valid, and vice versa. For example, a broken clock can be reliable (always showing the same wrong time) but it's not valid (it doesn't show the correct time). A test can be valid on its own but may not be "is reliable" if the sample size is not enough.
