Which notation should be used for the mean, SD, and median: mean±SD or mean (SD)? I usually use mean±SD notation for reporting values. I know that many people use mean (SD) notation and I understand why.
Right now in the document I am writing I am also reporting medians but I don't know which notation I should use for the 3 measures. Any suggestions? 
 A: Both conventions you mention are ambiguous - for example you can't tell whether the number after the $\pm$ is a standard deviation, a standard error, or the half-width of an interval. (a problem that has led to numerous questions on this site).
If you're publishing somewhere that offers precise guidelines follow those, but otherwise I suggest being explicit, for example: $``\text{median } 28.5,$ $\text{ mean } 31.2,$ $\text{ standard deviation } 3.6\!"$ -- then there's no possibility of misinterpretation.
A: I personally usually use Mean (Median) $\pm$ SD (IQR) [Min - Max]. That's quite maximalist, so may be a bit too much for certain purposes/readers, but is a quite logical grouping of indicators (central tendency $\pm$ dispersion, with traditional indicator first, robust alternative in parenthesis), I believe. (Minimum and maximum is of course added not because they're statistically especially important or good indicators, but because on the biomedical field it is often required for ''clinical'' purposes.)
