Discuss the difference in design and type of information gathered by correlational studies vs. true experiments
What will be an ideal response?
Answer: The following points should be discussed:
o Correlational studies involve one group of subjects, in which two variables are measured and correlated.
o True experiments involve a situation in which one variable is manipulated by the researcher (independent variable) and one variable is measured (dependent variable). Generally there are two groups in a simple design, and a statistical measure of how different the scores on the dependent variable are between the two groups is used.
o A correlational study can only suggest how two variables tend to go together or not.
o A true experiment allows a researcher to draw some conclusions about cause and effect
