You will need to find the middle number (mode) or all them could be.
* * * * *If there are three modes then so be it. One of the problems with the mode, as a statistical measure is that there may not be any or there may be many. A mode had little to do with the middle number - other than the expectation that, thanks to a central tendency, many distributions are likely to be clustered around their middle. But this is not always the case.
