You can gather all of the data that you want, but if you don't have a good way to analyze it you won't get much out of it. Google Sheets will only get you so far, so I'm poking around for better options. Some candidates:
- Statwing - an online statistics and analysis tool, currently in closed access
- Wizard - native OSX app for statistics
- R/Python - full programming languages with support for stats libraries
- Zenobase - online data aggregator with basic trend analysis
Hopefully more will pop onto the radar soon, but in the meantime I'm hoping to find some spare cycles to test a few of these out and see if there are any insights to be gained.
