Ethical Guidelines
Measures of Central Tendency
Data Distributions
Random Samples
100
This method involves detailed recordings of behaviors without the use of inference.
What is Naturalistic Observation?
100
This guideline ensures that participants are aware of any risks within the study and that they have a right to withdraw at any time.
What is informed consent?
100
This is the score that occurs most frequently.
What is mode?
100
If the mean is 75 and the standard deviation is 2, then 68% of people will score between these 2 values.
What are 73 and 77?
100
The type of distribution represented by this graph.
What is a negatively skewed distribution?
200
This method examines the existence and strength of relationships among variables, but is limited in that it cannot determine causation.
What is correlation?
200
This principle ensures that participants do not experience any lasting, ill effects?
What is nonmaleficence or do no harm?
200
In this data set, 85 represents this measure.
100, 85, 62, 74, 92, 81, 89
What is median?
200
About 34% of the population scores within this standard deviation of the mean in a normal distribution.
What is the 1st?
200
The measure of central tendency that is most impacted by the score of 55 in the following dataset: 20, 15, 19, 17, 55, 18
What is mean?
300
This method of research gathers and analyzes a collection of previously published, peer-reviewed studies.
What is meta-analysis?
300
Researchers must keep all participants anonymous by not publishing their names or other private, identifying information.
What is confidentiality?
300
The value 5.6 represents this measure of central tendency for the following data set: 1, 3, 6, 8, 10
What is mean?
300
In a normal distribution where the mean is 100 and the standard deviation is 15, Herbert must have this score to score at the 98th percentile.
What is a 131?
300
The type of distribution represented by this graph.
What is a positively skewed distribution?
400
This method of research is specifically bound to a singular person, group, or concept; it is beneficial for in-depth information about a concept, but cannot be generalized to a greater population.
What is case study?
400
In certain cases, it is allowed for researchers to withhold information from a study to uphold validity within the study.
What is deception?
400
This measure of central tendency is primarily used when there are extreme outliers among the data.
What is median?
400
This percentage of the population scored above Petunia, who is in the 74th percentile for height.
What is 26%?
400
The mean falls to this side of the mode and median in a negatively skewed distribution.
What is the right side?
500
The only method of research that can determine cause and effect through the comparison of two or more randomly assigned groups; one of which serves as a control, and the others are exposed to some level of independent variable.
What is experiment?
500
In the case that information has been withheld to uphold validity of the study, it is the responsibility of the researcher to inform participants of the actual nature of the study upon completion of their participation.
What is debriefing?
500
All three measures are equal in this type of distribution.
What is normal distribution?
500
In a normal distribution, this percentage of scorers will score within the second and third standard deviations above and below the mean.
What is 31.4%?
500
In situations like reporting household incomes, this measure of central tendency provides a more realistic understanding of what a "typical" income looks like.
What is the median? The mean may be inflated by a few extremely high earners (outliers).
