In a follow-up study, a researcher investigated whether there was a correlation between the average number of hours spent volunteering per month and self-reported life satisfaction.
The researcher randomly selected 20 participants from retirees registered at a local community center.
Each participant was asked, 'On average, how many hours did you spend volunteering per month over the past year?' They were then asked to rate their overall life satisfaction on a scale of 1 (extremely dissatisfied) to 10 (extremely satisfied).
The researcher hypothesised that there would be a positive correlation between the two co-variables.
Outline one reason why it was appropriate to conduct a correlation rather than an experiment in this case.
