Final answer:
Validity is about accurate measurement, while reliability focuses on consistency. Researchers aim for highly reliable and valid instruments.
Explanation:
Validity refers to the extent to which a given instrument accurately measures what it's supposed to measure. For example, in research, validity ensures that a test is measuring the intended construct, such as intelligence or academic performance.
Reliability, on the other hand, focuses on the consistency of measurement results. A test can be reliable by producing consistent results, but unless it is also valid, those results may not be accurate.
Researchers strive to use instruments that are both highly reliable and valid to ensure the credibility of their findings and conclusions.
