Similarity Matrix

A similarity matrix is a tool for comparison of numbers representing different data. The best example of this is a BMI chart. It takes two separate sets of data- Height and Weight, and compares the two and shows where the match up to represent someone who is underweight, healthy, overweight, obese, and extremely obese. Similarity matrices have 3 columns- the original 2 that are being compared, and the third is the column which presents the outcomes. This chart utilizes colors to show the comparison between the numbers and which area they correspond with. Green is the zone which everyone should be in, because that represents a healthy individual. Taller people can weigh more and still be healthy.
