2. Isaac wanted to know if the number of homework assignment completed in a science class affected a student's science grade. He collected the following data:
25 assignments completed = 95%
21 assignments completed = 89%
8 assignments completed = 50%
17 assignments completed = 75%
15 assignments completed = 65%
Independent Variable:
Dependent Variable:

Independent Variable: Number of Completed Homework Assignments

Dependent Variable: Science Grade

Explanation:

The dependent variable relies on the independent variable to change in order to make its own changes. The number of assignments are changing which results in the dependent variable (science grade) to change as well. That probably didn't make sense but I'm not a teacher.

it is stable as it is in group 0 which have full outer shells of electrons
