Strengths of Correlational Analysis
|
No manipulation of behaviour required- researcher merely measures and compares them, so fewer ethical problems. Enables precise and statistical analysis of degree of relationship- where experimental manipulation is not practical/possible
|
|
|
Weaknesses of Correlational Analysis

No cause and effect can be inferred. Since the researcher hasn't deliberately manipulated the variables we can't know which one is affecting the other or if it's being affected by a third
