Psychometrie SPSS Spiekbrief
Week 1

Schaalscores berekenen:

 Transform  Compute variable
o Target Variable = *naam geven; bv. lokfa_mean*
o Numeric expression = MEAN.n(… TO …)
 ‘n’ zelf bepalen
 alleen TO of , gebruiken




Relevante statistieken/report over onderzoeksgroep:

 Analyze  Descriptive Statistics  Descriptives …
 Schaalscores (bv. lokfa_mean etc.) naar de ‘Variable’s’
 Vervolgens Options  *mean, standard deviation, minimum en maximum
aanvinken*

Grafieken maken van de verdeling van de schaalscores:

 Graph  Legacy Dialogs  Histogram (of via ‘Chart Builder’)
 Schaalscore (bv. lokfa_mean) naar ‘Variable’

Schaalnormen maken:

Z-scores berekenen:

 Analyze  Descriptive Statistics  Descriptives
 Relevante variabele(n) (bv. lokfa_mean) naar ‘Variable(s)’
 ‘Save standardized values as variables’ selecteren
o De waarden zijn redelijk als de meesten tussen de -3 en 3 zijn; gecentreerd
rond het gemiddelde (=0) met 3 sd’s (sd=1)

,T-scores berekenen:

 Transform  Compute variable…
 Tscore = 10*z-score + 50
o Dus Numeric expression = 10*ZLokfaMean + 50
o De waarden zijn redelijk als de meeste tussen de 20 en 80 zijn; gecentreerd
rond het gemiddelde (mean=50) met 3 sd’s (sd=10)




Percentielscores berekenen:

 Transform  Rank Cases…
 Schaalscores (bv. lokfa_mean etc.) naar ‘Variable(s)’
o Rank Types  ‘Rank’ deselecteren & ‘Fractional rank as %’ selecteren
o Ties  ‘High’ selecteren
o Eventueel aantal decimalen aanpassen in Variable View
o De nieuwe waarden zijn redelijk als ze tussen de 0 en 100 liggen

, Normtabel maken:

 Analyze  Reports  Case Summaries…
 De 3 normscores naar ‘Variables’ en de schaalscore (bv. lokfa_mean) naar
‘Grouping Variable(s)’
o ‘Display cases’ deselecteren
o ‘Statistics’  ‘Mean’ van ‘Statistics’ naar ‘Cell Statistics’ verplaatsen

 ‘Number of Cases’ naar ‘Statistics’
