Goodness factor is a way of measuring how good something is. For example, a goodness factor could be used to measure how tasty a food is, how fun an activity is, or how nice a person is. To get the goodness factor, people usually look at different aspects of the thing they are measuring and then give it a score. For example, if measuring how nice a person is, people might look at things like whether they are helpful or friendly, how they treat other people, and if they are respectful. After looking at each of those things, they can give the person a score out of 10 and that score would be their goodness factor.
