Building a GroupBy Gallery to show average score

Hey all, I'm working on a gallery from a SharePoint data source.

My organization is doing a survey of all coworkers and wants a Power App dashboard built to review the data. The survey consists of 10 questions based on a strongly disagree to strongly agree scale. I've gone ahead and given point values to each of the choice optoins from 1 to 5.

I want to take a local collection I've created within the PowerApp, and group by all of the responses by their work location. Then ultimately get the average for each work location using all 10 questions in a single new AddColumn.

I keep trying to use the GroupBy function, but I keep erroring out.

ClearCollect(groupedData, GroupBy(colProviderData, "ProviderLocation", "GroupData"));
ClearCollect(finalData, AddColumns(groupedData, "TotalScore", Sum(GroupData, QuestionTwoValue + QuestionThreeValue)));

Any help or insight would be greately appreciated!

Just adding a clarification - you do not need quotes "" around the parameters and you can do it all in one action. Please mark @mmbr1606's post as the solution as the calculation was your main question.
ClearCollect( finalData, AddColumns( GroupBy( colProviderData, ProviderLocation, GroupData ), TotalScore, Sum( GroupData, QuestionOneValue + QuestionTwoValue + QuestionThreeValue + QuestionFourValue + QuestionFiveValue + QuestionSixValue + QuestionSevenValue + QuestionEightValue + QuestionNineValue + QuestionTenValue ) / 10 ) );

@mmbr1606,

I tried that, but the original ClearCollect on the groupedData is throwing an error.

It is saying "expected identified name" to both of the strings.
