You want to study the effects that music has on the ability to recall knowledge. Each individual in your study is given material to read on the same unfamiliar topic and then asked to take a factual quiz on the material. The control group is individuals who read the material and take the quiz in a quiet room. The experimental group is individuals who read the material and take the quiz in a room that has classical music playing. Is this an experimental study or an observational study. Explain your reasoning
What is experimental study because you are assigning individuals to the control group and the experimental group
