Correlation

Question 1

What is a correlation

Answer 1

Looking at the relationship between two co-variables to see if there is a significant relationship
+always uses quantitive date so results are easy to analyse
- quantitive data lacks depth and we can’t establish cause and effect

Question 2

What is the correlation coefficient

Answer 2

A number telling us how closely the co-variables in a correlation analysis are related between -1 and +1
Close to -1 is a strong negative correlation
Close to +1 is a strong positive correlation

Question 3

strengths of correlations

Answer 3

allows for further research to be completed based on the relationship found
easy to conduct as secondary data can often be used

Question 4

weaknesses of correlations

Answer 4

you can not establish cause and effect as you are looking at a relationship not measurement of difference
will require further research to conclude causation
you can only collect quantitative data, any conclusion made will lack detail and understanding into the relationship
