need field for “previous average” x_t-1
look into onChangeListener for when a question is answered (need to update all client UIs) (https://firebase.google.com/docs/firestore/query-data/listen)
current average calculated on the fly? weighted average (xt) also calculated on the fly
“running average” can be reused as xt-1 for the next session in the series

I've computed average statistics per session with a cloud function. Running average might be more tricky. I'll look into that in future.
