Is valid test always valid Why Give example?
A valid test is not always a reliable test. Validity refers to whether a test measures what it claims to measure, while reliability refers to the consistency of test results over time. For example, a test designed to measure mathematical ability may be valid if it accurately assesses math skills, but if the test yields vastly different scores when taken multiple times by the same individual, it lacks reliability. Thus, a test can be valid in content but still unreliable in execution.
A test may be reliable but not necessarily validIs it possible for a test to be valid but not reliable?
A test may be reliable but not valid. A test may not be valid but not reliable. For example, if I use a yard stick that is mislabeled to measure the distance from tee to hole in golf on different length holes, the results will be neither reliable nor valid. If you use the same stick to measure football fields that are the same length the result will reliable (repeatable, consistent) but not valid (wrong numbers of yards). There is no test that is unreliable (repeatable, consistent) and valid (measures what we are looking for).
Can a Test be valid but not reliable - ixzz1b3d5s1qa?
Yes, a test can be valid but not reliable. Validity refers to how well a test measures what it is intended to measure, while reliability pertains to the consistency of the results when the test is administered multiple times. For instance, if a test accurately assesses a specific skill but produces different scores each time it's taken, it is considered valid but unreliable. This scenario highlights that a test can effectively measure what it aims to measure, yet lack stability in its results.
Is a reliable test necessarily valid?

What is the difference between a valid test and a reliable test?
Reliable indicates that each time the experiment is conducted, the same results are obtained (accuracy). Valid indicates the experiment (or test) has controlled variables and used an appropriate method/model.
