What is a single-blind study?
When the subjects must close their eyes when receiving the treatment
When the subjects do not know who has the treatment
When the subjects and researchers do not know who has the treatment
When the information in the study is allowed to be sent to a single place
2
Well-done experimental studies can infer...
A cause-and-effect relationship
That there will always be a negative correlation
How many people deserve the treatment in the future
That the amount of individuals involved will be exponential
3
Which is the best explanation of a prospective observational study?
A study where an individuals' information can be distributed to the public
A study in which the individuals are tracked into the future
An observational study that became an experimental study
A study in which the individuals provide the most favorable answer
4
All of these are selection bias EXCEPT:
Non-response bias
Convenience bias
Undercoverage bias
Volunteer bias
5
Observational studies and experimental studies are the same.
True
False
6
A strata is a group of individuals in the population that are located near each other.
False
True
7
What is one reason that stratified random sampling and cluster sampling are different?
Stratified random samples use strata to differentiate rather than clusters.

The group of individuals who did not participate in the survey
The proportion of individuals who are involved in the statistic
The entire group of individuals we want information about
15
What is the best reason that explains why statisticians stratify?
To increase probability
To decrease the standard error
To consider it a systematic random sample
To reduce variation
