Acceptance Criteria:

• Clicking on one of these assessments will then have the system will provide a table listing students, with columns separating statistics, and a display of the class average for several statistics.
• When I click on a drop-down list containing a list of selected questions, I can select which questions I wish to include when calculating the average / exporting the table.
• When I click on a drop-down list containing a list of students, I can select which students I wish to include when calculating the average / exporting the table.
