Stappenplan: kort

Syntax opslaan
‣ Syntax opslaan als bureaublad
• File > new > syntax > *vraag1. > File > save as > op bureaublad
‣ In legende opschrijven op welk niveau variabelen gemeten zijn
‣ Bij elke opgave volgende vragen stellen;
• Op welk niveau worden variabelen gemeten?
• Hoeveel steekproeven zijn er?
• Is het een eenzijdige/ tweezijdige toets?
‣ Altijd data select cases en split file afzetten na elke oefening!
‣ Obstakels :
• N is te klein > KS uitvoeren
• Nulhypothese is contradictorisch met opgave: 1-p




ALGEMEEN

SELECT CASES
‣ Data > select vases > 'if condition is satisfied' > variabele

SPLIT FILE
‣ Data > split files > organize output by groups > niet normaal
verdeelde groep insteken

HYPOTHESES

p-waarde < alfa = Ho verwerpen = voldoende bewijs = significant
p-waarde > alfa = Ho aanvaarden = onvoldoende bewijs = onsignif.


Verband? Toets?

NOM / NOM
NOM / ORD Chi-kwadraat
NOM / RATIO


ORD / ORD Rangcorrelatiecoëfficiënt
ORD / RATIO


INT / RATIO Pearson

, One-sample T-test

Voorwaarden
‣ 1 steekproef (alle respondenten)
‣ Variabele = ratio niveau
‣ N> 30 , zo niet? -> KS test uitvoeren

Hypotheses vergelijken
‣ Ho: mu = 36
‣ Ha: mu 36 OF mu > 36 OF mu < 36

Wat als SPSS andere hypothese opstelt?
‣ 1-p-waarde
‣ Alfa = 1-.001 = .999 schrijven

Commando
Analyze > compare means&proportions > one sample t-test


Conclusie

A) tweezijdig of eenzijdig getoetst?
‣ Tweezijdig : two-sided p
‣ Eenzijdig: one-sided p


B) significant of onsignificant?
‣ P-waarde kleiner (<) dan alfa --> Ho verwerpen, significant,
voldoende bewijs

‣ P-waarde groter (>) dan alfa --> Ho aanvaarden, niet significant,
onvoldoende bewijs


APA-stijl

• t(df)= score
• P= .001
• Geen exacte p-waarde? <.001
