Amazon meters is a fun and informative way to showcase what people have been buying on Amazon.com. The meters can answer questions you may be interested in, such as:

• Which book series is more popular?
• Which game console do more people buy?
• Which format of this movie do people prefer?

Who chooses the Meters and how are the Meters chosen?

Amazon editors choose relevant groups of items for comparison based on current events, controversies, or just for fun.

How the Meters work

Meters compare sales of groups of items or just single items. The percentages shown are based on all sales for each group of item(s).

For example, let's say we want to compare two groups of products: Group A and Group B. Group A had 10 sales and Group B had 40 sales, with the total sales of both groups adding up to 50 sales. To figure out how Group A's sales compare to Group B's sales, we would figure out the percentage of total sales for each group. Group A's percentage would be 10 (Group A's sales) divided by 50 (total sales of both groups), which equals 20%; Group B's percentage would be 40 (Group B's sales) divided by 50 (total sales of both groups), or 80%.
