Test Variables -> Ok.
Independent-samples t-test
Analyze -> Compare means -> Independent Samples T test -> move dependent (continuous) variable
into Test variable box -> move independent variable (categorical) into section labelled Grouping
variable -> Define groups -> type numbers used in data set to code each group -> Continue -> OK.
Let op: bepaal of equal variances (not) assumed: grote Std. Deviation/ kleine Std. Deviation, als > 2,
dan zijn de varianties niet gelijk, bij < 2 zijn ze wel gelijk.
Let op: Als Sig. > .05 dan zijn de varianties gelijk.

for each subject into the box labelled Paired Variable -> if needed change the Confidence Interval
Percentage at Options -> Continue -> OK.
Chi² for goodness-of-fit
Analyze -> Nonparametric Tests -> Legacy Dialogs -> Chi-square -> move categorical variable into
Test Variable List box -> fill in Expected Values if needed -> Ok.

Type section -> click on Options and check Quartiles if you need the median scores -> Continue ->
Ok.
Let op: positive ranks met Sum of Ranks is T⁺.
