Answer 1

Analyse > compare means > independent samples t-test

Question 2

Compute paired samples t-tes

Answer 2

Analyse > compare means > paired samples t-test

Question 3

Answer 3

Create two variables and define grouping variable
Analyse> non parametric tests > legacy dialogs> 2 independent samples
Compute median
Calculate effect size

Question 4

Compute wilcoxon

Answer 4

Define two variables and enter the data
Analyse> non parametric tests > legacy dialogs > 2 related samples
Compute median
Calculate effect size

Question 5

Compute one way ANOVA

Answer 5

Analyse> general linear model > univariate
Options> descriptive statistics and homogneity tests
Post hoc> tick bonferroni or LSD
Calculate effect size

Question 6

Compute repeated measures ANOVA

Answer 6

Data one row per participant
Analyse> general linear model> repeated measures
Move each level of IV to within subjects variables
Options> descriptive statistics
Post hoc> paired samples t-test (move each variable until all comparisons are made)
Calculate effect size

Question 7

Compute independent factorial ANOVA

Answer 7

Data entered in 3 coloumns: One for each IV, one for DV
Analyse> general linear model > univariate
Options> descriptive statistics and homogenity tests
Calculate effect size
Conduct simple effects analyses: independent t-test and bonferroni
Data> select cases> select if condition is satisfied

Question 8

Compute repeated measures factorial ANOVA

Answer 8

Analyse> general linear model> repeated measures
Options> descriptive statistics and estimates of effect size
EM means> display means for IVs (not interaction)
Plots> add 2 plots vice versa> line chart
Simple effects: paired samples t-test and bonferroni> add every possible pair

Question 9

Compute mixed model factorial ANOVA

Answer 9

Analyse> general linear model> repeated measures
Options> move IVs under display means (not interaction)
Tick descriptive statistics, homogeneity tests and estimates of effect size
Simple effects: select cases> select if condition is satisfied
Compute paired samples t-test
Data> select cases> select all cases
Compute independent t-test
Bonferroni correction

Question 10

Compute Friedmans ANOVA

Answer 10

Analyse> non parametric > legacy dialogs> k related samples
Tick friedmans
Post hoc: wilcoxon and bomferroni correction
Compute medians
Calculate effect size

Question 11

Compute kruskal wallis test

Answer 11

Analyse> non parametric tests> legacy dialogs> k independent samples
Post hoc: compute mann whitney with bonferroni correction
Compute effect size
Compute medians: data> split file> organise output by groups> move IV under groups based on> tick sort file by grouping variable

Question 12

Square r
Calculate df by hand

Question 13

Compute partial correlation

Answer 13

Analyse> correlate> Partial
Tick two tailed and display actual significance level
Square partial correlation to get effect size
