Who uses star ratings?
Who uses star ratings? Each year, the Centers for Medicare and Medicaid Services (CMS) measures how well Medicare plans perform. The scale that's used is known as the Star Rating System. CMS gathers information from member satisfaction surveys, plans, and health care providers to give an overall performance rating for plans.
Do people trust 5 star ratings?
Interestingly, only 10% of consumers use a 5-star rating filter. Most people think it's too good to be true. According to research by Northwestern, purchases are most influenced by reviews with an average rating of 4.2 to 4.5 stars out of 5 — making this the ideal average star rating for purchase probability.
