How Many Blue M&Ms

The Research Question:
Given an assortment of 100 M&Ms, comprised of equal parts of blue, green, yellow, orange and red M&Ms, randomly stirred together in a bowl, what is the percentage of blue M&Ms that a child will choose, when allowed to choose 5, 10, 15 and 20 M&Ms.

Method for Measurement: I will use 6 subjects between the ages of 2 and 10, who will each choose the aformentioned amounts 5 times per amount (the experiment will occur on 5 different days and the children will choose all 4 amounts on each day). The M&Ms will always be displayed in the same bowl and will be placed in the bowl in random order and. The M&Ms will then be stirred randomly. The picking will occur at the same time each day.

Explanatory Viariable: # of M&Ms chosen

Response Variable: # of blue M&Ms chosen

Lurking Variables: Color preference

Hypothesis: I suspect that the percentage of blue M&Ms chosen will fall close to 20%, as I believe children that the majority of children are likely to chose at random.

After comparing the percentage of blue M&Ms chosen I thought it would be fun to compare this same data for each individual child, and then to compare these results against the other children in the group, perhaps using age as the explanatory variable.

Ethical Concerns: Cavities!!!

I was surprised to find in my measurements that there does not seem to be a consistent proportion of any color of M&M chosen. I realized quickly in doing my measurements that color preference played a much bigger role in the children's choosing than I had thought, as in subject JL who really liked the blue M&Ms.
