LATEST UPDATE
Placebo
A fake treatment given to control groups to mimic the experience of the experimental
group
Experiment
A carefully designed test, the results of which will either support or rule out a hypothesis
Falsifiable
Describes a hypothesis that can be ruled out by the data that shows the hypothesis
does not explain the observation
Testable
Describes a hypothesis that can be supported or rejected by carefully designed
experiments or observational studies
Controlled experiment
An experiment in which there are at least two groups, a control group and an
experimental group
randomized clinical trial
A controlled medical experiment in which subjects are randomly chosen to receive
either an experimental treatment or a standard treatment
Dose-response relationship
A relationship between the amount of a chemical or physical exposure, and the risk of a
specific outcome in an exposed organism
Case-control study
A type of epidemiological study to asses an association between an exposure and an
outcome
Epidemiological studies that show causation
Experimental studies and clinical trials
Epidemiological studies that show only correlation
observational studies and case-control studies
Epidemiology
The study of patterns of disease in populations, including risk factors
What distinguishes case-control studies from other epidemiological studies?
They are observational; looking at two groups who differ in only one factor; looks for
correlation
What is bias?
Any factor that causes distortion of genetic predictions
What are examples of bias?
Testing small samples, no diversity, looking for patterns
Recall bias
A type of error resulting from inaccurate recollection or reporting of past events
