# Statistical Science: Melt-in-Your-Mouth Math

A prediction project from Science Buddies

Observations and results
Were there one or two colors that were consistently the most common in each package of M&M's? What does this say about the likelihood of randomly selecting one of these colors versus a less common color when reaching into a package of M&Ms?

In statistics, how often a certain event happens is referred to as the frequency of that event. In this activity the events investigated were different M&M colors and their frequency was measured by counting their numbers within packages of M&M's, (which was the population investigated). Here you most likely found that in a package of plain M&M's the color with the average highest frequency was blue or orange (in other words, blue or orange was the most common color). These are generally the most common M&M colors in a package of the plain variety of the candies, typically making up around 18 percent to 31 percent of the M&M's in a package. (Because the percentages of other colors can be close and there is package-to-package variation, it is possible that this trend was not observed when investigating only three packages of M&M's.) The color with the average lowest frequency (or, in other words, the least common color) was probably brown, red or yellow. There was likely, however, some variation, and the most (or least) common color may have differed from package to package.

Cleanup
When you're all done with your statistical analysis, you may enjoy a tasty M&M snack! And don't forget to share with friends and helpers.

Perhaps the most useful lesson for a young person in this exercise is waiting until you're finished until you may eat any of the M&Ms! :-)
