The degree to which a research finding can be generalised
Ecological validity definition
The degree to which a research finding can be generalised to other settings
Population validity definition
The degree to which a research finding can be generalised to other groups of people
Historical validity definition
The degree to which a research finding can be generalised over time

What is internal validity concerned with
What goes on inside a study e.g whether the researcher tested what she or he intended to test
what is external validity affected by
The internal validity
What is external validity concerned with
The place where the researcher was conducted (ecological validity)
The people who are studied (population validity)
The historical period (historical validity)
What is the scientific cycle
Writing a hypothesis designing a study collecting data analysing results
