Samples
Sampling Bias
Experimental Study
Observational Study
100
An event is arbitrary if we know what outcomes could happen, but not which particular values will happen
What is Random
100
Every subject has the same likelihood of being chosen (use RNT)
What is Simple Random (SRS)
100
Some part of the population has been left out of the sample
What is undercoverage
100
This study examines a cause-and-effect relationship
What is an Experiment
100
Observing individuals and recording data without any intervention
What is an Observational Study
200
This models random events by using random numbers to specify event outcomes with relative frequencies that correspond to the true real-world relative frequencies we are trying to model
What is a Simulation
200
When the population is first sliced into homogeneous groups based on a characteristic before a sample is selected from each strata
What is Stratified
200
Some individuals don't respond by refusing to divulge information or they maybe absent
What is Nonresponse
200
A control group that gets no treatment or a fake treatment.
What is The Placebo Effect
200
Data that has already been collected in the past
What is Retrospective Study
300
The most basic situation in a simulation in which something happens at random
What is a Simulation Component
300
When the population is first sliced into groups based on a characteristic before one group is chosen and then a census is performed on that group
What is Cluster
300
Individuals may be dishonest with their answers
What is Response Bias
300
Used to avoid hidden bias the person conducting the experiment knows what kind of treatment the person is getting but the person receiving treatment does not know what treatment they are receiving
What is Single Blind
300
Data that is being collected in the present
What is Prospective Study
400
An individual result of a component of a simulation is its reaction
What is an Outcome
400
Every nth subject is chosen
What is Systematic
400
People that sign up or enlist themselves to answer questions
What is Voluntary Response Bias
400
In this experiment neither the subjects nor the people who have contact with them know which treatment a subject has received
What is Double Blind
400
Treatment where patients with syphilis did not receive treatment
What is the Tuskegee Syphilis Experiment
500
The sequence of several components representing events that we are pretending will take place
What is a Trial
500
the easiest method for the surveyor; sample readily available
What is Convenience
500
Questions that are asked with poor grammar or use complicated diction can result in response bias.
What is Wording of Question
500
There are only two treatments. In each block there is either: a single subject receiving both treatments or a pair of subjects each receiving a different treatment
What is a Matched Pair Design
500
An experiment has this while an observational study does not
What is Cause and Effect
