The research involves measuring the length of each participant's index finger and administering an IQ test to each. These variables are being measured to see if there is a relationship or correlation between them. The study is not manipulating any variables or randomly assigning participants to different groups, so it is not an experimental study. The length of the index finger is not the dependent variable nor is it being manipulated, so it is not B or D. Therefore, the best answer is A) correlational study.
