At 26 minutes in you explain that we calculate yield variance with standard mix and standard cost because we have already calculated Price and mix variance.
Does this mean that had we not have calculated those first we would need to calculate yield variance in another way?
(There are other ways of calculating it – it doesn’t matter how you do it in the exam, because they all end up with the same answer – but the way I show in the lecture is the easiest and most logical way.)
