One practical research exercise to gather data relevant to topics covered in biological psychology. This practical research exercise must adhere to ethical principles in both content and intention. In conducting the practical research exercise, you must:
design and conduct a correlational study to gather quantitative data and include descriptive statistics as analysis and a nonparametric test of relationship into aggression or body rhythms
make design decisions when planning and gathering data for a correlational analysis, including co-variables, operationalisation, ethical considerations, hypothesis construction and controls
collect, present and comment on data gathered, including descriptive statistics and graphical representation (scatter graph)
use inferential statistical testing (Spearman’s rank test) and explain the significance of the result and the use of levels of significance. Students must also be able to use a correlation co-efficient (strength/direction) to explain the relationship
consider strengths and weaknesses of the correlation and possible design improvements
write up the procedure, results and discussion section of a report.
A correlation into age/amount of time spent on social media and sleep.
A correlation to see if there is a relationship between height and a self-rating of aggressive tendencies.
