Before he uses this evidence to conclude that self-esteem reduces anxiety, Mr. Brown should first be reminded that d. correlation does not prove causation.
Explanation:
Correlation explains the mutual relationship or connection between two or more things. Causation reveals that one event is the result of the occurrence of the other event.
In correlation between the variables, the change in value of one variable doesn’t cause the change in value of another variable. In causal research, change in one variable causes change in value of another variable.
Mr. Brown has gathered evidence that the self-esteem of the students is negatively correlated with their typical levels of anxiety. Before concluding that the self-esteem reduces anxiety, Mr. Brown should confirm that correlation does not prove causation.
