Dear Johannes,

i had a short look at your https://statable.eu <https://statable.eu/> 
statistics website. This is
really excellent! Your approach to „ask questions“ is very suited
for beginners in statistics or simply people who even do not know that
they are just on the way to use statistical methods. I remember that I
installed pspp because I had the question if different lecturers
make a difference in exam results. On your website you start with a
question like that and then you propose the methods and the diagrams.

I started your example scenario „Schlaf and Konzentration“. Having
examples is of course a great help. You have this nice data analysis where
you give hints what might be a problem in the dataset like
„maybe w and weiblich mean the same thing? Shall I replace w with weiblich?“
I guess this one of the standard problems when you collect data in some
kind of spreadsheet. You can even jump to the cases where this happens.
I like that feature very much.

Your spreadsheet data visualisation is really nice. Easy to edit,
easy to read, easy to scroll. Your whole architecture is cool. I guess
many would have put the statistics calculations in the backend. You
use webassembly and do everything in the frontend. So your website can
be public and support a huge number of users. Very cool.

I used px4 flight control software for an autonomous drone. There you
log the data in the flight controller and analyze the data lateron on
a website by uploading the log data. For example:

https://review.px4.io/plot_app?log=c54c3a4c-5446-4343-a834-0bf928110b26

They use bokeh for drawing the charts. ArduPilot is a different flight
software and they use plotly for graphing. Both graphing tools allow
zooming and panning in the graphs which is very helpful for the flightlog
analysis. I did the scatterplot in pspp and therefore I know that it is
much more work to produce a nice graph than one might expect. An interactive
graph may be possible with plotly and if I remember correctly, this is
also something which is there as an addon for R.

And you draw nice looking graphs in your webview with different options!

You support the pspp syntax which is a good link if you want
to have more control over the analysis and if you want to try existing
examples. I tried the t-test example from pspp and noticed that the
graphs from syntax are not supported. It would probably be nice if the
graph syntax would render to something that can then maybe be modified as
in your graphs.

statable has the questions approach. When I had the data I wanted to
create some plots of the data. I guess many users are coming from excel where 
you can
create plots from data. A direct approach to analysis is the pspp syntax
window. I looked for a direct way to plotting in the data view. So it
took me a little while to figure out that plots are possible via the
questions. Maybe some direct way to plots might be nice.

In short: https://statable.eu <https://statable.eu/> rocks!

Thank you for creating that nice website and tool!

Best regards

Friedrich
