Q

STRENGTHS of correlation data

A

Make use of existing data(secondary)
High in ecological validity because it is real behaviour or experiences
Useful as a preliminary research technique- allowing researchers to identify a link that can further investigated through more controlled research
Can be used when it would be impractical/unethical to manipulate variables using another method
