Scenario 1

You run an afterschool program for middle-school students that operates for 3 months in the middle of the academic year. The program offers 1-1 tutoring, group-based skills-building learning workshops, and recreational activities. You are interested to learn how the program affects student success, which you define as improved grades (measured by GPA) and attendance (measured by days absent).

Due to space and staff limitations in the program, not all students are able to enroll into the program; You use a computer-generated lottery system to decide who gets to participate - whereby only half the students are able to participate while the remainder of the students attend regular afterschool activities provided by the school.

Data collection: You collect data from the students who participate in your program and as well as from those who did not. Among the data collected, you take note of student grades and school attendance 1 month prior to the program beginning and 1 month after the program ends.

Question:

In this scenario, what type of evaluation is being done?
