Introduction ecology lab correlating Hair colour to shoe size

Hypothesis: There is no correlation between a person's show size and the colour of their hair because a person's shoe size depends on their rate of growth and hair colour depends upon the genes the person receives at birth. 
Predictions: Shoe size will have no impact on hair colour. 
Methods: Each person's hair colour was either visually assessed or was asked about. The shoe size was asked to each person. Light brown and dark brown hair colour was generalized as brown.
