Statistics concept

[colinleach]

I have no idea how we would create an exercise to go with this. Too divisive: half the students (of the subset interested in Julia) already know this stuff and get bored with things that seem self-evident; the other half would need a semester-long course to understand it.

I'm not sure it matters much. If this gets merged, we can link to it from other Concepts, as I already did from randomness and will probably do from one I've not written yet (but may be called vector-operations).

The publicly launched
https://exercism.org/tracks/julia/concepts/vector-operations
"See the Statistics Concept for some examples."
has a broken link to
https://exercism.org/tracks/julia/concepts/statistics

Thanks for letting us know.

We could temporarily comment out the link in vector-operations, but I suspect that may not be the only optimistic, future-looking link to a concept (not just Statistics) that is not yet merged. I'll search for others.

I think a better approach might be to finish this PR and get it merged. That mostly means creating the introduction.md (currently an empty stub). Just copying the about.md is probably OK in this case, though that's something we try to avoid for concepts linked to concept exercises. We also need to move it from concepts.wip/ to concepts/ and add a config.json entry.

The Introduction is identical to the About - both are short. It's now in the correct directory, with a config.json entry.

However, this introduces another broken link, to randomness. Is it worth finishing #816 to fix this? That will eventually be paired with captains-log, when I have the time, energy and brain cells to port it. I already did an R draft, which gives me a starting point.

Is it worth finishing #816 to fix this?

It looks like the about.md is pretty well developed, so I guess if it is not too far off, it would be good to get it out.
