With an experiment a researcher is manipulating something (variables) in order to determine causal factors. Eg administering a drug to a treatment group and often a placebo to a control group to determine if the drug is effective.
A correlation is a statistic that indicates the strength of a relationship between any two variables. For example Height and weight, income and education level etc. A correlation will tell you if there is a relationship but not what causes the relationship. For example moderately drinking red wine is correlated with lower incidence of heart disease. However it is not clear whether drinking the wine is what causes the reduction in heart disease versus some other variable such as a moderate lifestyle or temperament.

A correlation is a measurement of the relationship between two or more variables such as test scores, gender, and so on.
An experiment is a deliberate manipulation of a variable to see if the corresponding changes in behavior result, allowing the determination of cause- and-effect relationships.
