SPSS vaardigheidstentamen blok 2

Toetsen voor gemiddelden hs 17 Pallant
Gepaarde t-toets; analyse – compare means – paired sample t-test – (variable 2 wordt van
variabele 1 afgetrokken, dus na-voor invullen) – evt bij options betrouwbaarheidsinterval
invullen – OK
effectmaat cohens d; gemiddelde verschil / sd van verschilscorer
Verschil score; transform – compute variabel – in numeric expression variabelen invoeren
(after - before) – in target variable naam invoeren (verschil score) – OK
One sample t-toets; (óf bij 1 groep óf met verschilscore van paired groepen) analyse –
compare means – one sampel t-test – (test of groep/verschilscore gelijk is aan 0, significant
is) test value invullen(meestal 0, let op nulhypothese) evt bij options
betrouwbaarheidsinterval invullen – OK
effect grootte cohens d; gemiddelde verschil / sd van verschilscore
Independent samples t-toets; analyse – compare means – independent sample t-test – bij
test variable variabel invoeren waarvan je verschil wilt meten – bij grouping variables de
groepen invoeren – define groups aangeven welke groep welke is (0,1,2) – continue – evt bij
options betrouwbaarheidsinterval invullen - OK – onderste rij interpreteren (bij eenzijdig
dubbelklikken op p-waarde voor precieze waarde om door 2 te delen)
effectmaat n2; (t-toets in kwadraat ÷ t-toets in kwadraat + df)

Toetsen voor categorische data hs 16 Pallant
X2-toets voor independence; analyse – discriptive statistics – crosstabs – variable in rows en
column zetten (welke waar maakt niet uit) – statistics – chi-quare en phi Cramer’s V
aanklikken – continue - OK
X2-toets voor homogeniteit; analyse – discriptive statistics – crosstabs – variabelen in rows
en column zetten (evt. cells – expected als je ook verwachte waarde wilt zien) – statistics –
phi, Cramers V en chi-square aanklikken – continue – OK
X2-toets voor goodness of fit; analyse – nonparametric tests – legacy dialogs – chi-square –
test variable list invullen – expected values  all categories equel (als alle variabelen gelijk
zijn)- OK
effectmaat; bij 2 bij 2 tabel; ᴓ = √X2/n
Bij meer kolommen; V = √X2/n  n = k-1  k = kleinste aantal rijen/kolom

Niet-parametrische toetsen hs 16 Pallant
Boxplot maken/mediaan zien; analyse – discriptive statistics – explore – afhankelijke
variabele invoeren en factor (groep) invoeren – OK
Rank-sum toets (independent); analyse – nonparametric tests – legacy dialogs – 2
independent samples – test variable en group invullen – OK
Singed-rank toets (dependent); analyse – nonparametric tests – legacy dialogs – 2 related
samples – after en before invullen (after-before) – OK
effectmaat; |z|÷√n (absolute z, dus zonder negatief getal)
