10 items, 7 regular and 2 irregular. How the equation should be?
And the 10th item is...?
The equation is absolutely analogue.
The only vatiable value is the "6", that depends on your scale.
6: if it is a scale 1-5
8: if it is a scale 1-7
And of course you change the codes of your subquestions.
In this example I used
R001, R002, ... for Regular items
I001, I002,... for Irregular items.
