I totally failed to consider that the set could have multiples of the same element.

Don't be hard on yourself...

One thing that helped me on this is to take couple of minutes to think through (like - what is given and what is asked to find) on the stimulus prior to evaluating the given statements. I would equate this to pre-thinking for CRs or re-phrasing the stimulus strategies..

Happy preparation :-)

For Statement 1) since the median of the set is lowest element, the set can be either an 1, 2, or 3 element set.
Here are few examples {1}, {2,2}, {3,3,3} - Not Sufficient

I eliminated Statement 2 as Not Sufficient for basically the same reason you stated. I interpreted Statement 1 as meaning it only had one element and picked A. I totally failed to consider that the set could have multiples of the same element.

Unfortunately the GMAC doesn't use the strict mathematical definition of a set. Under the strict definition, every element of a set is unique. According to this question, the GMAT considers sets only in the colloquial sense.
