How are reliability and validity assessed? Whether you're launching an exciting new product or conducting scientific research, validity can determine success and failure. While wasting money on a lousy product is a concern, lack of validity paints a much grimmer picture in the medical field or producing automobiles and airplanes, for example. Businesses would lose money, and patients couldn't rely on medical treatments. Without it, the results couldn't be trusted, and products would likely fail. Every product and discovery, from innovative medical breakthroughs to advanced new products, depends on accurate research to be dependable. Research is used to improve life for humans. They can be compromised by asking the wrong questions or relying on limited data. Studies must be conducted in environments that don't sway the results to achieve and maintain validity. However, collecting accurate information can be more of a challenge. Researchers rely on carefully calibrated tools for precise measurements. Validity in research is the ability to conduct an accurate study with the right tools and conditions to yield acceptable and reliable data that can be reproduced. Valid research strives to eliminate the effects of unrelated information and the circumstances under which evidence is collected. In the most basic sense, validity is the quality of being based on truth or reason.
