Variables
What is Independent Variable?
Studies outside of the lab in the "real world", can not be replicated, can not control extraneous variables
Both variables are affected in the same way
What is positive correlation?
When one sample of participants receives each condition of an experiment
What is repeated measure design?
An extraneous or third variable that lowers the validity of the experiment which hazes the line between IV and DV
What is Confounding variable?
The variable that is measured after the manipulation of the Independent variable
What is dependent variable?
Can test for significance, can determine a cause and effect relationship, method of study for behavior,
What is laboratory experiments?
One variable increases while the other decreases
What is Negative Correlation?
When members of a study are randomly selected to one condition of the experiment
What is Indepentant Sample Design?
What is order effects?
Variables where all other variables stay the same or constant
What is control variable?
Experiments are made/grouped based off of a common trait or behavior (ex IV: gender, culture, age)
What is Quasi experiments?
It is not possible to know which variable caused the behavior
What is Bidirectional Ambiguity?
An independent sample design in which participants are not randomly selected to sample experiments, they are pretested with regard to the test, it guarantees each condition has a full range of ability
What is matched pair design?
Researchers can control for order effects, ensures the order of conditions don't affect the study
What is counter balancing?
What is extraneous variable?
Refers to an IV that is environmental and outside of the researchers control, pre-test/post-test design, measured before and after variables are introduced
What is natural experiments?
No pattern exists between variables
What is Illusory Correlation?
Testing any few things at the same time
What is concurrently
When the participant becomes skilled in the experiment from practicing
What is practise effect?
1. When variables are written in a way that it is clear what is being measured
2. Procedures are written in enough detail and can be replicated
2. What is standardized?
You want to do a study of helping behavior on a city's metro subway. You decide you are going to have someone faint on the subway to see if anyone will help. In one condition the person is well dressed and in the other the person is not. What kind of experiment is this?
WHat is a field experiment?
Seen in correlation research when it is impossible to know is x causes y or y causes x, if they interact to cause behavior or there is a third variable
What is Bidirectional Correlation?
When an individual is compared only to themselves
What is participant variables?
Prediction that says the IV will not effect the DV
What is null hypothesis?
