- AConfounding
- BBias
- CStatistical significance

What kind of bias is in this study by his poor planning alone?

- BMeasurement Bias
- CGeneralizability Bias
- DInternal Validity
3For studies that measure the association between exposure and outcomes, non-differential misclassification has what effect on the risk ratio?
- ADecreases the RR
- BIncreases the RR
- CHas no effect on the RR, only the OR
- DBrings it closer to 1.0
4Differential misclassification bias can either inflate or attenuate the effect estimates of association in relation to 1.0
- AVerdadero
- BFalso
5Which of the following is not part of the observer-related measurement biases?

11Drinking 8 oz of wine each night has been linked to a decrease in heart issues, stress, and a marked increase in overall happiness. Scientists first found the relationship to these benefits with 1 oz. Then, the results were proven with 2 oz. Then, 4 oz, and finally 8 oz.

- AReproducibility
- BExponentialism
- CMarked Increase
- DBiologic gradient
12This picture is an example of what?
- ACritical Criteria Pyramid
- BResearch Evidence Pyramid
- CHierarchal Evidence Pyramid
- DAssociated Epidemiology Pyramid
13Students at KCUMB conduct a small experiment to determine the association between the variety of meals the residents of CT cook and the size of the kitchen appliances. They find that there is no association, so they fail to reject the null hypothesis (H0). In reality, though, students here are extremely limited to what they can cook because of the small size of the ovens in the rental units. What kind of error is this?
- AType II Error (beta)
- BType 1 Error (alpha)

- B3
- C2
- D1
- E0

- BExpedited
- CFull board
- DEntire board
