Number of bins

default Scott User given:

Number of bins (classes) for histogram. •

Show values ?

Shows the graph coordinates.

Computes, from (possibly many) user's data, some simple statistics.

This explores the size of the data accepted. Supply data in American or European style (such as through copy & paste from Excel).

The graph shows a histogram of the data. If the number of bins, 'nbins', is not given ('nbins' = 0), then, from the N data, R being the data range and s the standard deviation, 'nbins' is computed as: "default", R ⁄ (0.3 s); or Scott's rule, R N^1⁄3 ⁄ (3.5 s)
