There are three scoring options for check all that apply questions: recommended scoring, partial credit scoring and all or nothing scoring.
Recommended scoring is the default scoring method. When creating each check all that apply question, McGraw-Hill Education decides whether the question will be scored by partial credit scoring or all or nothing scoring, based on the question's content. If your assignment contains multiple check all that apply questions, they may not all be scored the same way. If you select this option, you are allowing each check all that apply question to be scored the way that McGraw-Hill Education recommends.
Partial credit scoring is a flexible scoring method that awards students credit for each element answered correctly. If you select this option, all check all that apply questions within the assignment will be scored this way.
All or nothing scoring is a less flexible scoring method that awards students either full credit or no credit. Full credit is awarded only when students correctly answer all elements of the question. If none or some of the elements are answered correctly, students receive no credit at all. If you select this option, all check all that apply questions within the assignment will be scored this way.
Example: Let's say your check all that apply question contains 10 elements, of which five are correct. Each correct element is worth one point, so your question is worth five points total. When using partial credit scoring, a student who selected four of the five correct options will receive four points. When using all or nothing scoring, that same student will not receive any points.
