Correlational Research
What is a correlational study?
A statement made by researchers that predicts the relationship between two variables
What is experimental hypothesis
This kind of experiment helps to determine if there's a cause and effect relationship between two variables. This type of experiment has the maximum control.
What is a Laboratory experiment
This type of variable causes change in another variable. This variable is changed on purpose.
What is an independent variable
A design where one sample of participants receives each condition. Participants are only compared to themselves.
What is the Repeated Measures Design
A relationship between 2 variables where both variables are affected in the same way
What is a positive correlation
Whether or not a researcher can take their findings and apply them in the real world or to other groups of people.
What is external validity?
This type of experiment is performed in the real world and cannot be replicated easily. Extraneous variables cannot be controlled in this experiment.
What is Field experiments?
This is the variable that is being measured.
What is the dependent variable
A design where participants are randomly allocated to one condition. Each group is tested in their respective condition and then results are compared.
What is the Independent Sampling Design
A relationship between two variables where one variable increases and the other decreases.
What is a negative correlation
An evaluation about how certain you are that your experiment is valid
What is internal validity
The independent variable occurs naturally and is not randomly assigned in this experiment.
What is Quasi-experiments
These are other aspects of the experiment that could have an effect on the results so they are kept the same.
What is a control
A design where groups are made based on participants with similar traits.
What is the Matched Pairs Design
A relationship where researchers believe that variable A causes a change in variable B but in reality there could be a variable C that is causing the change in variable B
What is illusory correlation
When you make it clear what you are measuring in the experiment
What is Operationalization
In this experiment, the independent and dependent variables occur naturally. Measured before and after the variable is introduced.
What is a Natural experiment?
Outside variables that could impact the results of the experiment in an undesirable way.
What is extraneous variables
When the participants and the researchers don't know which group is the experimental or controlled group
What is Double-Blind Control
A relationship between variables where you can determine correlation because no independent variable is being manipulated.
What is bidirectional ambiguity
Writing down the experiment procedures in detail so that the experiment can be repeated
What is Standardization
An experiment where you manipulate the independent variable but do so in a not controlled environment
What is a true experiment?
This effect occurs when participants of an experiment answer in a way that makes them look good to the researcher
What is the Social Desirability Effect
When participants results are skewed due to boredom or fatigue. Participants could also continue getting better because they've done the experiment multiple times.
What are Order Effects
