B is correct
4. No prediction and no abstraction. No A and D.
C is correct: he has a hypothesis and so a theory
5. B: that is the only time you have an intervention
6. C (experiment) is out: because there is no intervention. Longitudal: 3 types. Cohord:
no. panel: NO, we follow one sample over time. But we have every time another

Independent variable; cause variable = relationship affect.
True experiment: 2 groups and 2 measurements in time, randomised
You can measure extraneous = out of your reach but you can measure them.
1.is true
2.not true
A is correct
9. Study design is: 4: Experiment, case, longitudal, cross sectional
There is no relation between the data collection and the study design.
Content analysis, observations, and questionnaires do not require qualitative
measurement.
Regularities: averages of a year (E.g.)
