I will have coloured M&Ms and participants will choose 20 M&Ms very quickly. Each of the participant’s chosen M&Ms will be placed in a zip-lock bag with their favourite colour written on it. Their chosen M&Ms will be compared with their favourite colour and then recorded.
Independent and Dependent Variables:
The independent variables are the participant's favourite colour as their colour preference will be the cause as to which coloured M&Ms they will pick.
The dependent variable is the chosen M&Ms by the participants and the number chosen for each colour as it is the effect of the participant's favourite colour.
Experimental Controls:
The controlled variable I kept was the number of M&Ms of each colour to be placed before each participant so that all participants will be able to have and equal chance of choosing their M&Ms. I also controlled the age group and gender so that all participants were as equal as possible.
Risk Assessment:
There is very low/minimal risk when performing this experiment. As no food consumption is needed, the only risk involved would be allergic to chocolate by touch.
Validity and Reliability:
The validity of this experiment is high as it does measure participant's favour towards their specific colours and results will show if they had chose more of their favourite colour than others or not.
The reliability of this experiment is fairly accurate as majority of people tend to become bias towards their preferenced colours and therefore if another test was conducted, the results will be very similar.
