Typen onderzoek
Cross-sectioneel onderzoek is een onderzoek waarbij men een dwarsdoorsnee van de totale populatie in de steekproef opneemt. Hoe groter de steekproef, hoe betrouwbaarder. Cross-sectioneel onderzoek wordt vaak gebruikt in de beschrijvende statistiek:
- Steekproef wordt samengevat in één getal
- Data wordt kritisch bekeken (zijn er uitbijters?)
- Hoe groter de steekproef, hoe betrouwbaareder
Naast beschrijvende statistiek heb je toetsende statistiek:
- Hoe ver ligt het gemiddelde in de steekproef van het gemiddelde in de populatie?
- Dit noemt men de standaardfout
- Vaak is het verschil “niet significant”
