One thing I'd point out here, philosophically, is that Excel is a program designed to trick you into thinking you're not "coding" when you use it. SQL is much more nakedly 'code', but it's very much the same type of code as Excel formulas; more of your current skills will transfer than you might think.
Vanilla SQL doesn't do much in terms of visualization, summary statistics, or hypothesis testing. And since smartsurvey delivers results in CSV and SPSS, there's little reason to go into SQL for this sort of thing.
@cbrachyrhynchos @Nentuaby @gendercensus @doxxy @foxxy This. I spend a fair bit of time at work banging on SQL to make it do stuff that everyone wishes we could just do in R, it's bad, you should not do data analysis with SQL unless a whole-ass extremely stubborn corporate IT bureaucracy has tied your hands to the keyboard to make you.
It will also be much easier to download RStudio than to set up a postgres server.
@cbrachyrhynchos @Nentuaby @gendercensus @doxxy @foxxy That said, even though R is a fine way to start learning to code, with a lot of tutorials available geared very specifically towards people with no coding experience who want to analyze some data... it is still coding.
MS Excel will support the amount of data you're talking about.
