Statistical Significance
Statistical significance is a way to be confident that research findings are real and not just due to chance. It's like having enough evidence to be sure about a conclusion. Market researchers use this concept to determine if their findings from surveys, tests, or experiments are reliable enough to make business decisions. For example, when testing if customers prefer a new product version over an old one, researchers need to know if the preference is genuine and not just random. Think of it as the difference between hearing a few positive customer reviews versus having solid proof from hundreds of customers that consistently show the same preference.
