Variances

Hi,

I have a question concerning the sales variances. While following the lecture in Chapter 14, i noticed that the Example 4 asks for sales margin variance. It is a synonym for sales volume variance right?

And for sales quantity variance, it is the equivalent of sales yield variance( i don’t know if i phrased it well).

Are there any other synoym which might come up in exam for any other variances?

Thanks
