In response to Elsey’s question, my quick answer is that I’ve seen histograms with varying bin widths but not with equal probability. Elsey did some searching and found this on varying binwidth histograms, with references going back to the 1970s.
WebTo find the percentile of a specific value in a normal distribution, find the z-score first by using the formula. Z= (x-μ)/σ where μ is the mean and σ is the standard deviation of the data set. Then look up that z-score on a z-score table. The corresponding number in the z-score table is the percentage of data below your value.
