ECOL 2050 lab 1 -

Randomly selected individuals were observed on campus walk in York University. The Researches observed 3 variables: gender, glasses, and hair colour. Gender was recorded as observed. Glasses present were recorded as any type of glasses (sunglasses, corrective glasses) that were visible on the individual. Finally, hair colour was recorded as observed, and if there were multiple observable colours the individual was questioned about their natural hair colour. 25 individuals were recorded. When a group passed by only one individual from the group was recorded to avoid biased sampling.
