Correlation

Question 1

Correlation

Answer 1

It is a technique designed to analyse the relationship between 2 variables

Question 2

Positive correlation

Answer 2

As one co-variable increases, so does the other co-variable e.g. If time studying and grades are co-variables with a positive correlation, the more timey you study, the higher your grade

Question 3

Negative correlation

Answer 3

As one co-variable increases. the other co-variable decreases. E.g. If time playing games and grades are co-variables with a negative correlation, The more time you play games, the lower your grade.

Question 4

Strengths of correlations

Answer 4

They are cheaper and less time consuming than experimental research.
They are useful for investigating a topic that would be difficult to study experimentally for ethical reasons
Using co-variables rather than manipulation is less interventionist and more ethical

Question 5

Weaknesses of correlations

Answer 5

Cause and effect cannot be established as we cannot confirm that one variable causes another or that there isn’t a third variable involved.
