What is the effect of an outlier on the MAD (mean absolute deviation) of a data set. Choice A) An outlier does not change the MAD. Choice B) An outlier always increases the MAD. Choice C) An outlier always decreases the MAD. Choice D) An outlier can either decrease or increase the MAD. Personally, I'm debating between choices B and D. What do you think?
The answer is D because a outlier when given a set of data could possibly have the chance of increasing or decreasing the MAD Hope this helped :)
