Correlational research and correlation coefficients
- 3 things to know
- Component 01
Overview
Recall questions on how data is obtained for correlational analysis, co-variables, positive, negative and no correlation, scatter diagrams, interpreting correlation coefficients, the strengths and limitations of correlations, and the third-variable problem.
What you need to know
Answer each one before you reveal it.
Why might a correlational analysis miss a genuine relationship between two variables?
What is a correlation?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What is a correlation?
Model answer
A relationship between two co-variables in which changes in one are associated with changes in the other.
- 2
How is data obtained for a correlational analysis?
Model answer
Two measurements are taken from each participant, one on each co-variable, and the paired scores are then analysed for a relationship.
- 3
Why are the two measures in a correlation called co-variables rather than an IV and a DV?
Model answer
Neither is manipulated by the researcher, so neither can be said to produce the change in the other.
- 4
Describe a positive correlation.
Model answer
As the value of one co-variable increases, the value of the other tends to increase as well.
- 5
Describe a negative correlation.
Model answer
As the value of one co-variable increases, the value of the other tends to decrease.
- 6
What is meant by no correlation?
Model answer
There is no consistent relationship between the two co-variables, so changes in one are not systematically associated with changes in the other.
