Easy to use statistical package with many options available in an intuitive way (ease-of -use).The data file can be easily imported from other applications such as Microsoft Excel or Google Drive/Docs which is really useful when you need access multiple files at once! The user interface could have been simpler but it's not difficult so no real issue here either; very good product that I've found extremely helpful during my Masters studies where we needed some simple yet robust stats packages able solve our problems within minutes instead spending hours solving them manually would take us days if using excel alone! Great tool overall especially since there are free trials allowing students like me who may spend quite considerable amount off time per study period doing these things without breaking their bank account ;).
