SPSS samenvatting blok 3 Experimenteel en Correlationeel Onderzoek

Scatterplot maken;
Graph  chart builder  simple scatter  onafhankelijke variabele naar x-as, afhankelijk
naar y-as  OK
Correlatie berekenen;
Analyse  correlate  bivariate  2 variabelen in variable box  pearson aanvinken 
options  execute cases list/pairwise  continue  OK
Regressielijn toevoegen in scatterplot;
In scatterplot  dubbelklik  elements  fitline at total  lineair  apply
Enkelvoudige lineaire regressieanalyse uitvoeren;
Edit  options  onder output vink aan; no scientific notation for small number in tables 
OK  analyse  regression  lineair  independent en dependent variable invoeren 
method; enter  statistics; selecteren wat gevraagd; interval, r squared, descriptives, part
 continue  OK
Meervoudige lineaire regressieanalyse uitvoeren;
Analyse  regression  lineair  dependent en meerdere independent variabele invoeren
 method; enter  statisticts; selecteren wat wordt gevraagd, save; statistieken voor
outliers, options; list/pairwise  continue  OK
Meervoudige regressievergelijking formuleren;
Constante = b0 andere predictoren invullen voor ; b1 b2 bij X1 en X2  Ydak = constante +
predictor X1 + predictor X2
Semi-partiële correlaties opvragen;
Bij meervoudige regressie; statistics  part and partial correlation selecteren
Unieke bijdrages beoordelen;
In output in coefficients table; part per predictor kijken welke bijdrage
R, Rs, Rpb en phi berekenen;
r = Sxy/SxSy  covariantie delen door sd x en y; covariantie = (∑(Xi-Xgem)(Yi-Ygem))/N-1
rs = ∑ (rXi - rXgem)/sd x (rYi - rYgem)/sd = ∑ZxZy/N-1  rangscores – gemiddelde rangscores
rpb = √t2/t2+df
phi = AD – BC / √(A+B)(C+D)(A+C)(B+D)  schuin in tabel delen door marginale totale
Betrouwbaarheidsintervallen opvragen;
In enkelvoudige en meervoudige regressie; save  mean (individual = voospellingsinterval)
 procent aangeven  continue  OK
Hiërarchische lineaire regressieanalyse uitvoeren;
Analyse  regression  lineair  variabele in dependent, eerste variabele in independent
 next  twee variabele in independent etc.  statistics  estimates en model fit 
continue  OK
Tabellen aanpassen met Pivoting Trays;
In uitvoer bestand  dubbelklik  enkele cel of meer selecteren  rechter muisknop 
pivoting trays  statistieken naar linksboven slepen  OK
Celwaarden in tabellen aanpassen;
In uitvoer bestand  dubbelklik  enkele cel of meer selecteren  rechter muisknop 
cell properties  aanpassen wat gevraagd wordt  apply  OK
Betrouwbaarheidsinterval en voorspellingsinterval in scatterplot weergeven;
In scatterplot  dubbelklik  elements  fitline at total  interval aanvinken (mean of
individual)  apply
