a Upon completion of studying each chapter in their social studies course, students are asked by their teacher to write a brief essay on their analysis of the chapter content and how they could apply the concepts in real life. To encourage her students to perform well on each essay, the teacher gives a token if the student obtains a mark of at least 90%. Students, particularly those not receiving a token, could attempt for one at the end of each subsequent chapter. Then, to receive a special prize at the end of the term, a student should have at least 10 tokens to exchange for the prize. Based on this study, identify the following:

Independent variable (1.25 pts)

Dependent variable (1.25 pts)

Whether the dependent variable is discrete or continuous (1.25 pts)

The scale of measurement used to measure the dependent variable (1.25 pts)
