Correlations

Question 1

Correlation

Answer 1

Illustrates the strength and direction of an association between two co-variables.

Question 2

Scattergram

Answer 2

One co-variable is on the x-axis, the other is on the y-axis.

Question 3

Types Of Correlation

Answer 3

-Positive correlation- co-variables increase together
-Negative correlation- one co-variables increases, the other decreases.
-Zero correlation- no relationship between variables

Question 4

Differences Between Correlations And Experiments

Answer 4

In an experiment the researcher manipulates the IV and records the effects on the DV. In a correlation there is no manipulation of variables and so cause and effect cannot be demonstrated.

Question 5

A03 (Useful Starting Point For Research)

Answer 5

E- By assessing the strength and direction of a relationship, correlations provide a measure of how two variables are related.
E- If variables are strongly related it may suggest hypotheses for future research

Question 6

AO3 (No Cause And Effect)

Answer 6

E- Correlations are often presented as causal, e.g. by the media, when they only show how two variables are related.
E- This leads to false conclusions about causes of behaviour
