more features
No IV or DV, just to co-occurring variables (co-variables)
As there is no IV to manipulate we cannot establish cause and effect.
We don’t know which variable is causing the other, we just know there is a relationship between them.
Like Self Report and Observation, there is no manipulation of data, conditions or groups in correlations.
Correlations can be both the primary method or secondary technique.
Self reports and observations can both be used as a way to gather data on variables, and then see if there is a relationship between them.
-
obtaining data - In observations, experiments and self-reports, data is found first hand.
-
secondary data information can also be found from pre-existing sources. - you aren't directly testing the participant
e.g if you wanted to see the relationship between maths ability and money earned, you would not necessarily need to test participants’ maths ability directly. You could simply find out their GCSE maths score.
