Question

If you have 256 data points, how many classes (bins) would sturges' rule suggest

Answer 1

Since Sturge's Rule states that the optimal number of bins is equal to the 1 plus 3.3 log(n), where n is the number of data points, the estimated solution (since you can only have whole bins) is to provide 6 bins, each storing 42 to 43 data points.
