Question: A ground breaking study has reported strong relationship between income and happiness, and even claimed that high income earners were generally happier than the low income earners. While you agree that money may contribute to comfort and even luxury you do not agree that money brings happiness. Plan your own study to explore if there is in fact any link between income and happiness. Include six study designs and what each would involve. (For example, how you will carry out the study, what sort of study participants you will need for each design, what information should be collected to investigate this link, what measure of association/effect can be obtained from each design, name one confounding factor for each study design and tells how or why it will affect the findings of your study)

*One paragraph for each study design

a) Cross-sectional study

b) Case Control study

c) Prospective Cohort study.

d) Retrospective Cohort study.

e) Quasi-experimental study.

f) Randomized Controlled Trial
