What is the dependent variable?
Addressing a situation and developing a plan you think will work to complete the goal.
What is testing a hypothesis?
Studies examining naturally occurring relationships between variables.
What are correlational studies?
Studying behaviors that occur in the real world.
What are descriptive studies?
An idea about the relationship between two things that can be measured.
What is a Hypothesis?
In this type of design, the researcher manipulates an aspect of the environment and observes the effects of this manipulation.
What is an experiment?
Surveys assessing personality traits and job satisfaction.
DAILY DOUBLE
What is industrial-organizational psychology?
A statistic measuring the strength and direction of a relationship.
What is a correlational coefficient?
Observers of descriptive studies cause human error disadvantages.
What is observer bias?
Assigning participants randomly to groups in an experiment increases internal validity.
What is random assignment?
Experiments answer these questions.
Hot weather and violence are correlated, but hot weather does not cause violence. A third variable relates to them.
What is the third variable problem?
Correlations do not address causation.
What is the thrid variable problem?
Some studies describe individuals over some time.
What are case studies?
The variable in an experiment that is purposely altered.
Double-blind studies prevent this bias from affecting results.
What is experimenter bias?
Observing children on a playground to understand peer relationships.
What is naturalistic observation?
The symbol used to show the correlation coefficient.
What is r?
Observer effects occur when participants change behaviors because they know they are being watched.
What is reactivity?
How results of an experiment apply to the real world.
What is external validity?
Experimental methods can be limited in this area.
What is sample size?
Taking time to see if your plan to complete a goal was successful.
What is analyzing data?
Correlations show a relationship but not causality.
What is an illusory conjunction?
Descriptive methods answer this question.
