Let's say that a high school developed a new study lab that students could use with no restrictions. When the school year ended the administration team discussed if the lab helps to increase the grade point average. The team selects a pool of students at random and divides them into two groups; those who used the computers and those who did not. They conclude that the group who used the computers had a higher GPA vs those who did not. Can the administration determine that using the lab increased the GPA? Why or why not? Should this study be redesigned to make any changes why or why not?
