Variables and Hypothesis Mallory Olivier “Teachers Rule!” Variables: Independent Variable – The grade level of the students surveyed will change Dependent Variable – The students answers to the survey if they like their teachers or not Controlled Variable – The questions on the survey will remain the same throughout the experiment Hypothesis: If I survey all students in grades K-5th grade to see if they like their teacher then I think the students in the younger grades such as K-2nd grade will like their teacher more than students in the higher grades.
