Practical

Question 1

Aim

Answer 1

To conduct a correlation to the relationship between testosterone (shown by finger ratio) and aggression (shown via aggression questionnaire)

Question 2

Method

Answer 2

The participants completed a questionnaire asking 30 questions about their aggressiveness and measured on a 5 point scale giving them a total for aggression. The second variable involved measuring the length of their ring finger and index finger and measuring the ratio between the two (it was done in this order to avoid them figuring out that their testosterone was being measured and effecting the results on their questionnaire).

These two variables were then plotted onto a scatter graph to measure correlation and a Spearman’s Rho calculation was conducted. All results were kept confidential and participants were both debriefed and given the right to withdraw at any point.
