Is there a correlation between an individual's shoe size and hair colour?

Methods: Students (21) were surveyed about their shoe size and hair colour. This was done in an indoor classroom setting in Room 118 in the Lumbers building, located in York University Keele Campus. Procedure was carried out by verbally asking each student individually first their colour of hair, recording the (categorical) data in a table (similar to the one found in the spreadsheet). Then their shoe size (discrete) data was recorded with same method (verbally asking each student their size of shoe) in the same table. All data recorded was solely based off the information the subject provided. Hypothesis: There is no correlation between the shoe size of an individual and their hair colour because these two variables are independent of one another. Prediction: There is no direct correlation between the hair colour and shoe size of an individual
