Educational psychologists investigate the impact of different types of instruction on learning. In one study, researchers taught

a math lesson to 9th-graders using the "Inventing to Prepare for Learning (IPL)" instructional cycle. A second group of students received traditional "tell and practice" instruction. After the lessons, both groups studied a worked example of a math problem on their own. Then they took a test that included problems like the worked example. The journal Cognition and Instruction published the results in 2004. Pick the best description of this study:
(A) an observational study of an association between two variables
(B) an experiment to establish a cause-and-effect relationship between two variables
(C) No answer text provided.
(D) an observational study to make an estimate or a claim about a population
