Measures of Central Tendency
Measures of Association
100
Examples of this type include systematic reviews and meta-analyses.
What is Tertiary Sources?
100
Consists of categories, where the order of the categories is arbitrary.
What is nominal data?
100
When both researchers and participants know which treatment is being administered.
What is open-label?
100
The point where 50% of values fall above and 50% fall below
What is median?
100
The probability of an unfavorable event occurring in the treatment group vs. the control group.
What is relative risk?
200
PubMed is an example of this type of literature.
What is secondary literature?
200
Interval is a type of this data.
What is continuous data?
200
In this kind of study, all patients are given both placebo and active doses in alternating periods.
What is double-dummy?
200
The most common value in a distribution.
What is mode?
200
Can be calculated by: 1 / (% risk in control group) – (% risk in treatment group)
What is number needed to treat?
300
The Pharmacist's Letter and treatment guidelines are an example of this type of literature.
What is tertiary literature?
300
Gender is considered a type of this data.
What is nominal?
300
When neither the participants nor the researchers know which participants belong to the control group, nor the test group.
What is double-blind?
300
This measure is very sensitive to outliers.
What is the mean?
300
Measures how much risk is reduced in the treatment group compared to the control group.
What is relative risk reduction?
400
This literature presents original thinking, reports a discovery, or shares new information.
What is primary literature?
400
NYHA functional class is an example of this type of data.
What is ordinal data?
400
In this type of blinding, the investigator would know which groups the participants belong to, but the participants do not.
What is single-blind?
400
The difference between the 25th and 75th percentile of data
What is interquartile ranges?
400
Difference between the control group’s event rate and the treatment group’s event rate.
What is absolute risk reduction?
500
This is a service of the U.S. National Library of Medicine.
What is PubMed?
500
Height and weight are an example of this type of data.
What is continuous?
500
This could be considered an extension of double-blinding when even the committee monitoring response variables is not told the identity of the groups.
What is triple-blinding?
500
The measure of how much the data vary from the mean
What is standard deviation?
500
Can be calculated as Risk in treatment group / Risk in control group.
What is relative risk?
