1Test 1 Question 6. A group of patients are looked at with regard to a risk factor for heart disease. They are divided into those who have the risk factor and those who do not.

- ACohort study
- BCase–control study
- CClinical trial
- DCross-sectional survey
- ECrossover study

- BSecondary prevention
- CTertiary prevention
- DMalingering
- ENoncompliance
3Test 1 Question 105. A type I error occurs when:

- BA positive value means that one variable moves the other variable in the same direction
- CIt can give information about cause and effect
- DIt indicates the degree of relationship
- EA negative value means that one variable moves the other variable in the opposite direction
