6. Give one strength of the statistical infrequency defintion
the criteria is too strict and narrow
it's more objective than the other definitions: this means behaviour is easily generalised to other people
you can establish cause and effect
7. Describe one limitation of the statistical infrequency definition
It has good internal validity: uses experiments which involve controlled and standardised procedures
problem with misdiagnosis: certain behaviours are statistically common e.g. approx 10% of the population will experience depression
it's subjective: means the definition is subject to bias interpretation of what is abnormal
8. Name one strength of Jahoda's definition
can be easily replicated

Comprehensive and takes a positive view: big range of factors makes it a good tool for establishing mental health
good internal validity

negative attitudes towards the self; tiredness; autonomy; observer discomfort
10. What is a problem with the 'deviation from social norms' definition
Lack of standardised procedure: means the definition has a lack of control so lacks internal validity
It is culturally relative: social norms differ between culture, so lacks generalisability
The criteria is not comprehensive: cannot be used as a way of describing abnormality
