_ A researcher wants to test the hypothesis that there is a positive relationship between the freedom university students experienced as children (measured on a 20 item scale which asks people about things like whether they were allowed to ride their bikes around the neighbourhood unsupervised as children, etc. vs being taken to and from supervised activities - a high score indicates a high level of freedom) and their time management skills at university (measured on a 15 item scale, a higher scores indicating better time management skills). She has also collected information on age of subjects as research has shown that older people tend to have better time management skills, so she wants to control for this. What would be the most appropriate statistical technique to use to test the above hypothesis? Select one: a. Partial Correlation O b. Factorial ANCOVA Cc. One-way ANCOVA d.
