Laboratory studies are a type of primary marketing research that are often used by larger consumer products companies. The downside, for small businesses, is that they cost from $50,000 to over $100,000 per test leg. On the other hand, these tests have a high degree of reliability and correlation with actual market performance when the test product, pricing, and advertising are similar to those actually used in the real market. They can save companies many millions of dollars in potentially wasted marketing spending by showing weaknesses in product, advertising, pricing, or other variables prior to real-world marketing.
