Procedure:

· Open the bag

· Pour out the bag

Sort the M&Ms into piles by color
Count the M&Ms
Recount the M&Ms
Write the number of different color M&Ms on the board
Type the number of different color M&Ms in the chart

Observations:

I noticed that most of the M&Ms had the didn’t have the same number of a certain color in a different bag. In bag 1 and 3 there was the same number of blue M&Ms. In bag 2 and 3 there was the same number of red and orange M&Ms, but all the other numbers were different.

Data Table

Color	Bag 1	Bag 2	Bag 3	Bag 4

Blue	15	20	15	14
Red	5	8	8	2
Yellow	17	11	19	13
Brown	7	9	3	8
Orange	4	6	6	8
Green	9	6	7	12
Total	57	60	58	57

Analysis and Conclusion

I learned that not every bag of 1.69oz plain M&M candies have the same amount of each color. I came to this conclusion because the data shows that there is a different amount of candy sorted by color in each bag. I believe M&Ms are sorted in a factory, then placed in bags. They are not sorted by color to make sure that there is the same amount of each color.

Math Fun with M&Ms

Using Excel we found the mean for each color, the found the median and mode. We went to the M&M web site and found a chart that states what percent of each color is in a bag of M&Ms. We again used Excel to calculate the percents in our bags and then found the mean, median and mode for the percents.
