Taste Preception Science Project

I was wondering if two volunteers would be too little for this experiment. I will have them drink the same beverage but each are different colored. After, they have to write down the juice they think they are drinking. Should I have more test subjects, or is two enough?

In general, if it is possible, it is always better to have more volunteers for an experiment like this so you can gather more data points. The more data you have, the stronger of a conclusion you can draw. With just two volunteers, it is difficult to see any trends that may become more apparent with 5-10 volunteers.

Hope this helps,
