Verband ó oorzakelijkheid
Verbanden zijn niet noodzakelijk causale (= oorzakelijke) verbanden
Verband betekent niet automatisch dat de ene variabele de oorzaak is van de andere!


T OPIC 1: C ORRELATIE , REGRESSIE EN TIJDREEKSEN
1. CORRELATIE- EN REGRESSIEANALYSE
1.1. CORRELATIEANALYSE

, Negatief lineair Geen verband Positief lineair verband Negatief niet-leniar
verband verband

Verband tussen twee variabelen X en Y nagaan
• X onafhankelijke variabele, Y afhankelijke variabele
• Verband of statistische samenhang à Correlatiecoëfficiënt = r
o -1 ≤ r ≤ +1
R = -1 R = +1 R=0
perfect negatief verband perfect positief verband geen verband

Schijnverbanden = verbanden tussen twee variabelen die geen echte oorzaak-gevolgrelatie hebben.
Dit betekent dat de correlatie tussen twee variabelen niet het gevolg is van een direct oorzakelijk
verband, maar door toeval of een verborgen derde variabele.
• Bv: ijsjes verkoop en doden




Perfect negatieve samenhang Perfect positieve samenhang
Negatief verband: als X stijgt dan daalt Y Positief verband: als X stijgt dan stijgt Y
Perfect: punten liggen op 1 lijn Perfect: punten liggen op 1 lijn
àr=-1 à r = +1
Bv: prijs en vraag Bv: prijs en aanbod

• Aard van afhankelijkheid = samenhang
• Graad van afhankelijkheid = punten ligging

Binnen consumentengedrag vind je zelden verbanden die groter zijn dan 0,70 omdat het menselijk
gedrag multigedetermineerd is (dus door verscheidene factoren wordt bepaald).
• |r|= 0,10 à zwak verband
• |r| = 0,20 à matig verband
• |r| = 0,50 à sterk verband

2. REGRESSIEANALYSE
Onderzoekt de invloed van een onafhankelijke variabele (X) op een afhankelijke variabele (Y).

• Lineaire regressie Y = a + bX wordt gebruikt om een trendlijn te berekenen.
