To find out how well VP solved the tasked, we calculate the accuracy for train
and test phase.

#+begin_src python
condition = "random"
df = pd.DataFrame([tools.total_accuracy(data[condition][vp], procedures) for vp in data[condition].keys()], index=data[condition].keys(), columns=["train", "test"])
df

Most subjects have an accuracy of over 95% in both training and test phase.
Some however are notably lower, under 90% in either training or test phase, or
both.
This could be a systematic misunderstanding of specific equations, that are
present in both, or only one of the two phases.
To investigate, we look at the per procedure accuracy per subject.

#+begin_src python
condition = "random"
proc_accs = [
    tools.count_correct(data[condition][vp], data[condition][vp].keys(), procedures)
    for vp in data[condition].keys()
]
for vp in proc_accs:
    for proc in vp.keys():
        vp[proc] /= len(next(iter(data[condition].values())).keys())
df = pd.DataFrame(proc_accs, index=data[condition].keys())
df

We can see that most vp have around 2 procedures with accuracy of around 50%
