If you were to pick a number on the number line at random, there is literally a 100% chance that it will be irrational (probabilities with inifinities are spooky). Yet, we almost never encounter irrational numbers for we can’t write them down. The shapes we know best - lines, parabolas, circles, spheres - are the needles, for they can be expressed by simple equations....

Let $$n_i$$ be the number of reviews that item $$i$$ gets, and let $$r_i$$ be the naive average rating of item $$i$$ Let $$N$$ be the total number of reviews across brands, i.e. $$N = \sum_{i} n_i$$ Let $$R$$ be the average rating over all items across brands, i.e. $$R = \frac{1}{N} \sum_{i} n_i r_i$$...
