Question

Dr. Kingston, a psychologist, is examining how a student’s reading speed is differently affected by two variables: being tutored by a teacher’s assistant and being tutored by a computer-based reading program. In this experiment, which of the following is the dependent variable?

A. the student’s reading speed
B. the teacher’s assistant
C. the computer-based reading program
D. the grade that the student belongs to

Answer 1

Answer:

The answer is A. the students' reading speed.

Explanation:

In experimental research, an independent variable is expected to change a dependent variable. In the example, whether the students are tutored by an assistant or a computer is predicted to affect their reading speed.

An easy way to distinguish both terms is to say: independent causes change in dependent.
