Question 859840: A research group interested in understanding the effect of listening to classical music on learning mathematics conducted a study. One hundred students were randomly assigned to one of two groups. The first group listened to classical music as they learned a new lesson. The second group learned the same lesson with no music playing. Both groups were tested on the new material to determine how much they learned. The results for the two groups were compared. What kind of study is this?
I am not sure if this is observational or experimental. Can you please tell me and tell me how you know so I can know how to find the answer to the others like this? Thank you SO much for reading this and taking the time to help!

In an experiment investigators apply treatments to experimental units
In an observational study investigators observe subjects and measure variables
of interest without assigning treatments to the subjects.
This particular research was experimental(1st group given music, 2nd music withheld)
