A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
the below information corrects me:
"Excel 2008 and 2011 versions do not include the Analysis Toolpak add-on, which is required for many PHStat courses. Any Mac users will need to install a third-party add-on recommended by Microsoft to replace this function (StatPlus:mac LE).
PHStat is not currently compatible with Excel of Mac 2016. (It remains compatible with Microsoft Windows Excel 2016, still in its preview edition.) The workaround is to use Excel/Office 2011."
so they admit that I cannot use PHSTAT if I have Excel 2011 for MAC,
if I have Excel 2016 for MAC I can use it but this time Excel is not coming with DATA Analysis Toolpack.
I was wishing to use them at the same time on any version of Excel for Mac, but anyway I realized that Data Analysis seems to be a subset of PHSTAT and moreover; if I want to use it on some cases I have to install both Excels and use thems in turns on same Macbook. (open one close other one)
