A null hypothesis is a statement that predicts no difference or correlation in the findings.
Alternate Hypotheses
An alternate hypothesis is a statement that predicts a difference of correlation in the findings.
Independent Variable (IV)
The variable/s the experimenter manipulates (i.e. Changes).
Dependent Variable (DV)
A DV is the variable which is measured by the experimenter after they have manipulated the IV.
Extraneous Variable (EV)
Extraneous variables are other variables (not the IV) which could affect the results of the experiment.
Experimental designs

Describes the way in which a group of data cluster around a central value. There are three measures of central tendency: the mean, the median and the mode.
Median

Mean

Range

Validity
Refers to the accuracy of a test’s ability to measure what it is supposed to measure.
