sample-size is one of our most popular tags (54th), categorizing 232 threads as of July 14, 2013. However, the topic sample size is very broad and not very distinctive, in my opinion. There are a number of other tags that are related to this topic or overlap some aspects of the topic, including:
- small-sample (tag wiki)
- big-data (tag wiki)
- large-data (tag wiki)
- power-analysis (tag wiki)
- power (tag wiki)
- underdetermined (tag wiki)
At present the tag wiki excerpt for sample-size reads:
Use this tag for questions where it is desired to know an appropriate sample size to perform a test or analysis or when the sample size is relevant to the question.
I'm not sure this provides the ideal guidance on the use of the tag. It seems to me that if someone is trying to figure out what sample size they need for their study, the most appropriate tag might be
power-analysis, although I can also see how someone might say that tag should only be used for questions about power analyses (say, the difference between a-priori and post-hoc power analyses) instead.
Moreover, skimming down the list of questions tagged with
sample-size, perhaps about half are tagged with one of the above as well, and it's not clear what having the tag
sample-size in addition adds. There are, of course, cases where the other tags do not occur and
sample-size seems appropriate, but quite often the manner in which each of those questions is related to sample size seems fairly idiosyncratic.
I'm wondering how threads should best be organized with respect to these categories.
For what it's worth, my suggestions would be:
- Copy the excerpt and tag wiki from
big-data(which is somewhat more informative) to
large-data(which seems to be the preferred tag), and make
- My preferred tag wiki excerpt for
This tag is very ambiguous. Please use only if one of the following is not more appropriate: [small-sample], [large-data], [power-analysis], [power], or [underdetermined].
However, this may not be the best approach, and I'd prefer to open this up to community discussion here than make changes on my own with the only oversight being conducted by two suggested edit reviewers.
