-
Independent variable?
Variable that is manipulated by the experimenter,can’t be effected by Dependent variable
-
Dependent variable?
Variable that is just measured; its value depends on other variables in the study
-
Correlation-Positive?
one variable goes up, the other does too,Negative Correlation= as one variable goes up, the other goes down. Zero Correlation= there is no relationship between the two variables. Measured in -1 through +1. .+5 is a good correlation
-
Field Study?
High realism, hard to manipulate variables, lots of other things occurring, sometimes can be illegal (rigging a game show).
-
Controlled experiment?
Experiment with a control group and an experiment group, using both groups to measure a placebo effect within the group.
-
Random Assignment?
Assures a higher success rate for a study when each person is randomly assigned to a control or experiment group
-
Random Selection?
Choosing participants at random so that everyone has a chance of representing the population, allows for generalization of the population.
-
Main Effect?
Main effect of the study on our participants, from the results what is the main conclusion
-
Interaction?
like a correlation, it’s a result from the survey that can be derived usually from a graph.
-
Pre-test?
a test issued to participants to try and measure their feelings or whatever before they are involved in the experiment, so we can compare with a post test, not a good idea for a study, can make participants much more nervous and aware of the experiment.
-
Confound?
An outside source that may be interacting with the results of the experiment, something that may be manipulated accidently. Basically other things going on in the experiment.
-
Experimental group?
the group that is being tested, their results determine the result of the study.
-
Control group?
the group that is being issued a placebo, we should already know their results before they occur.
