Method

1. The M&M's were equally portioned into the large bowl.
2. The first participant was asked to quickly pick out 20 M&M's, using a two-finger pinch and placing it into a zip-lock bag.
3. The first participant was then asked their favourite colour which they wrote on their zip-lock bag.
4. The M&M's was replaced by the same-colored M&M's that the participant took from the bowl (If 3 red and 5 brown M&M's, replenish the bowl with 3 red and 5 brown M&M's, not from the participant's bag).
5. The test was repeated multiple times whilst the bowl was replenished with the same-colored M&M's as each participant removed after every trial.
6. The bags were sorted and the M&M was tallied into their favourite colour groups. The tallying was finished and the results were recorded in a data table.
7. The data was normalized by calculating percentages of each color picked for each "Favorite Color" category. The total number of M&Ms chosen for each "favorite color" was added. The percentages was calculated in a new data table. The number was divided by the number of M&M's chosen for a single color by the total number of M&M's chosen.The answer was  then multiplied by 100.
8. A graph called a histogram was made for each "Favorite Color" M&M. A scale of percentages from zero to 100% was written on the left side of the graph (y-axis). A series of M&M colors was written on the bottom of the graph (x-axis). A bar was drawn for each color up to the matching percentage.
9. The histogram step was repeated for each of the favorite M&M colors
