Definition
Observational: Epidemiologist observes exposure and outcome without controlling either Descriptive: Epidemiologist collects information to characterize and summarize health event (who, what where & when) Analytical: Epidemiologist compares groups to identify risk factors (why & how) Experimental (Clinical): Epidemiologist controls exposure of subjects to an intervention and observes the outcome |

Definition
A type of prevalence study;
Exposure and disease measures obtained at the individual level;
Single period of observation;
Exposure and disease histories collected simultaneously;
Both probability and non-probability sampling methods used...In examples of this type of study, used the word "survey" a lot. |

| Testing Statistical Significance determines how likely...? |
|
Definition
| the study results could have occurred by chance |
|
|
Term
| What is the "null hypothesis" when testing statistical significance? |
|
Definition
| That there is no association between exposure and outcome. If the p-value is less than <0.05, than you reject this hypothesis! |
