WebJan 10, 2024 · Although histograms are useful for visualizing distributions, it’s not always obvious what the mean and median values are just from looking at the histograms. And while it’s not possible to find the exact mean and median values of a distribution just from looking at a histogram, it’s possible to estimate both values. WebThe estimate of the mean is the weighted average of mids: In [60]: mean = np.average(mids, weights=n) In [61]: mean Out[61]: 9.9763028267760312 In this case, it is pretty close to the mean of the original data.
