What is generalisability?
“Generalisation is concerned with the application of research results to cases or situations beyond those examined in the study.”
Collis and Hussey 2003
What does this mean?
Put simply, generalisability asks: can the results of the research be applied more generally and more widely than the study itself or are they only relevant to the specific context of the study?
Generalisability is concerned with whether research findings can be generalised beyond the specific context in which the research was conducted. A study may be valid in one setting but not in another and in this instance the research results would not be generalisable.
Whether or not generalisation will be possible in each case is a product of the type of study, the research setting and specific characteristics of the study.
