  • What is an independent and dependent variable?

    Independent: characteristic being observed or measured, that is hypothesized to influence/cause an event or outcome (dependent)

    Dependent: outcome (disease), it's dependent on the independent to occur.

  • What does epidemiology measure?

    - exposures

    - outcomes

    - confounders

  • What is the exposure and outcome?

    Exposure: the risk factor or potential cause of a disease or illness, ie. the independent variable.

    Outcome: the possible result from the exposure.

  • What is the confounding variable?

    The third variable that affects both the exposure and outcome. A variable that can cause or prevent the outcome of interest. They're adjusted for in statistical analysis. Ex. age, sex, SES.

  • What are the 2 basic facets of research design?

    Manipulation of the study factor - exposure of interest is controlled by the researchers.

    Randomization of study subjects - chance determines the likelihood; no control over the subjects which removes bias.

  • What are the two types of observational studies?

    - Descriptive

    - Analytic

  • What do ecologic studies analyze?

    The group/the whole population.

  • What is the difference between an ecologic comparison study and an ecologic trend study?

    Trend: examines exposure rates among different groups.

    Comparison: examines changes in disease within the same community.

  • What is the ecologic fallacy?

    Observations made at the group level may not be representative at the individual level.

  • A cross-sectional study is a type of ___ study.

    A cross-sectional study is a type of prevalence study.
