Inferential statistics
A way of analysing data to determine the likelihood that any difference/correlation is statistically significant
Statistical significance
Suggests that results are not due to chance- or it is extremely unlikely they are
p Value
The probability that results were due to a chance result. In psychology we accept 5% (0.05)
Type I error
A false positive- when alternate hypothesis is rejected incorrectly and the null hypothesis is accepted incorrectly
Type II error
A false negative- when the alternate hypothesis is rejected incorrectly and the null hypothesis is accepted incorrectly
Calculated value
The result of an inferential statistical test
Critical value
The number in a data table that you must compare with your calculated value
Related design
An experimental design where the participants in one condition are similar to those in another- either repeated measures or matched pairs
Unrelated design
Independent groups design- the participants in one condition are not similar or related to those in the other conditions
Test of difference
A comparison between conditions
Test of association
An investigation into a correlation or relationship between co-variables
