Calculating the common-scale rating: We divided the adjusted T-Score, which is on a 100-point scale, by 20 to convert the third-party rating to a common 0-5 point system.To ensure that the mean was equal across all data points, we added our desired scoring mean (between 0 and 10) to the T-Score to create an adjusted T-Score. Calculating the T-Score: We used a T-Score calculation to convert the Z-Score to a 0-100 scale by multiplying the Z-Score by 10.We then subtracted the mean from the company’s rating and divided it by the standard deviation to produce the Z-Score. To determine the Z-Score for each third-party rating of a company, we calculated the mean of the ratings across all companies evaluated by that third-party source. The Z-Score is negative when the data point is below the mean and positive when it's above the mean a Z-Score of 0 means it's equal to the mean. Calculating the Z-Score: The Z-Score represents a data point's relation to the mean measurement of the data set.News score using the method outlined below: We then used the Z-Score to create a standardized U.S. To balance the distribution of scores within each source’s scale, we used a standard deviation (or Z-Score) calculation to determine how each company’s score compared to the source’s mean score. The 360 scoring process first converted each third-party rating into a common 0 to 5 scale. We used the scoring methodology described below to convert these systems to a comparable scale. Before including each third-party data point into our scoring equation, we had to standardize it so that it could be compared accurately with data points from other review sources. The third-party review source data were collected in a variety of forms, including ratings, recommendations, and accolades. (b) We standardized the inputs to create a common scale. Therefore, some sources were excluded from our model.

Please note that not all professional and consumer rating sources met our criteria for objectivity. Sources with a sufficient number of quality consumer ratings and reviews were included in our scoring model. News also reviewed published consumer ratings and reviews of refrigerator providers. News believes consumers benefit most when these opinions and recommendations are considered and analyzed collectively with an objective, consensus-based methodology. Rather than relying on a single source, U.S. However, professional reviewers often make recommendations that contradict one another. We consider several of these third-party reviews to be reputable and well-researched. Many independent refrigerator evaluating sources have published their assessments of refrigerator companies and their products online. (a) We compiled two types of third-party ratings and reviews: The ratings are not based on personal opinions or experiences of U.S.
Our scoring methodology is based on a composite analysis of the ratings and reviews published by credible third-party professional and consumer review sources. News’ 360 Reviews team applied an unbiased methodology that includes opinions from professional reviews as well as consumer reviews. We created objective 360 Overall Ratings based on an analysis of third-party reviews. Research shows that these are the most important criteria for people shopping for a refrigerator.Ģ. We then compared the available refrigerators across several criteria, including cost, total capacity, Energy Star certification, spill-proof shelves, in-door water and ice dispenser, ice maker location, fast cool, Wi-Fi connectivity, smart features, ADA compliance, refrigerator capacity, and freezer capacity.
We found 40 refrigerators that stand out in terms of volume of searches and research among consumers, as well as across the different rating sources. News analyzed and compared a variety of publicly available data, including internet search data, to determine which refrigerators Americans are most interested in. We researched the companies and products people care most about. The following describes our 360 approach to researching and analyzing refrigerators to guide prospective consumers.ġ.
