Do You Eat The Red Ones Last? Jenna Talib Mulgrave School Floor Location : J 225 D
My experiment looks to determine what impact, if any, colour has on a person’s food choice. I will be testing eight different colours of the exact same food. The subject will be given a choice to select one of eight different smarties, all of which taste exactly the same. My experiment will test different independent variables including different age groups (12-14) and the gender. I am measuring the number of times a specific coloured smartie is selected by a sample of subjects. I will control the variable of taste and colour by ensuring that all items taste the same and that the same colours are offered to each subject. The uncontrollable variables include a subject that is colour blind (cannot distinguish all colors of smarties) and any subjects that are allergic to chocolate or other ingredients used in smarties. Another uncontrollable variable is the emotional state or hunger level of the subjects.

If 100 subjects, equal number of males and females, were given the choice to pick their most desired one of eight different coloured smarties (red, purple, pink, orange, yellow, green, blue and brown), then a higher percentage of subjects will select the red smartie, followed by the blue smartie, then the pink smartie, the yellow smartie, the green smartie, the purple smartie, the orange smartie, and finally the brown smartie. According to a commercial printing company, the most desirable colours to the human eye, in order are: red, blue, pink, yellow, green, purple, orange, and brown. The hypothesis supports that the colour of a smartie that a subject will choose as their most desired and and their least desired will follow the order of what science tells us is the most desirable colours to the human eye.

When I conducted by experiment, I emailed a few Grade 7, 8, and 9 teachers to test their class on my experiment. I recorded the data using a table with separate rows and columns for the age and gender for all of the subjects. I asked each subject their age, gender and also their least and most preferred smartie colour preference. I then recorded the information on the piece of paper with the table on it.
After conducting this experiment, I found that the purple smartie colour is the most desired smartie colour for female subjects as 15 out of 50 female subjects chose the purple smartie. I found that the orange smartie colour is the most desired smartie colour for male subjects as 10 out of 50 male subjects chose the blue smartie. The least desired smartie colour for both female and male subjects is by far the brown smartie as 50 out of 100 male and female subjects (half) chose the brown smartie.
In conclusion, my experiment did not support my hypothesis as I predicted that the majority of the male and female subjects would pick the red smartie colour as red proves to be the most appealing colour to the eye.
