This is the average of number in a data set
Mean
Getting permission from participants
consent
A testable prediction, often implied by a theory
Hypothesis
An observation technique in which one person is studied in depth in the hope of revealing universal principles
Case Study
Experiments are they only type of research that show what?
Cause and effect
The middle number in a data set
Median
Describing the purpose and methods of the experiment after it is completed
Debriefing
When someone is given a fake treatment, but they believe it is helping.
Placebo Effect
observing and recording behavior in a lab setting
Laboratory Observation
The perception of a relationship where none exists
illusionary correlation
Finding the number that occurs most frequently in a data set
Mode
Protecting data from being shared
Confidentiality
These test subjects are not usually exposed to the experimental treatment
A control group
an experimental procedure in which both the research participants and the research staff are ignorant about whether the research participants have received the treatment or a placebo
Double blind procedure
The only way to ensure a study is able to be replicated and represent a population
Random Sampling
The difference between the highest number in a data set and the lowest number in a data set
range
A promise to protect people's physical and psychological health
Do-No-Harm
The experimental factor that is manipulated
Independent Variable
This research method watches people and animals without them knowing, in order to study behavior
Naturalistic Observation
Doing research by studying many related studies that were done previously
Meta-Analysis
Measures the amount of variation in variable around a central mean.
standard deviation
An oversight organization that reviews experiments
Independent Review Board
Factors that can influence the experiment but are not accounted for in the dependent and independent variables.
Confounding Variables
The research method that shows naturally occurring relationships
Correlational research studies
When data is clustered towards the low end of the data range (i.e. low test score), the data is considered:
positively skewed
