Reliability and validity are related qualities but independent

Reliability and validity are related qualities but independent. They are similar to the terms "precision" and "accuracy," respectively. A wind-up clock that does not work is accurate (valid) twice a day. But it lacks precision (reliability). A digital clock that is always 5 minutes slow is never accurate (valid) but is very precise (reliable). Elaborate on the assessment instrument used in your project to ensure validity and reliability.
