<p>The two questions by tomclark seem to be on topic -- "<em>What is the best way to test if the number of Males in group 1 is significantly greater than group 2, which is 0?</em>" is <em>clearly</em> a statistical question (I am astonished to think that anyone would maintain that's off topic here. In need of clarification, perhaps, but definitely within our scope).</p>

<p>Unfortunately they're duplicates of each other, so one should be deleted or the two should be merged. Unfortunately, one has been extensively edited -- so it has more information -- while the other has the longer answers; I'll have to think about how to tidy that up.</p>

<p>While I definitely disagree with deleting both of those, the other one does look off topic and should be closed (which I just did). </p>

<p>Either way, the dplyr tag doesn't seem to be needed; it's not relevant to the statistical question being asked.  (whuber's suggestion of keeping the tag but warning that a question using it may be off topic is an interesting proposal, and defnitely worth considering)</p>
