[Channel-talkdata] question

Hi, I have been taking the Data, Statistics and Probability course and
have a couple of questions.
1. Why would a statistician prefer to use the SSE over just the sum of
the absolute values of the errors? The sum of the abs values would be
just as easy to compare as the squares so why go thru the extra trouble
of squaring the value?
2. When would it be better to compare data using M.A.D vs. variance or
Standard deviation?
