%X This study aims to establish a rationale for the
Rice University rule in determining the number of bins in a histogram. It is
grounded in the Scott and Freedman-Diaconis rules. Additionally, the accuracy
of the empirical histogram in reproducing the shape of the distribution is
assessed with respect to three factors: the rule for determining the number of
bins (square root, Sturges, Doane, Scott, Freedman-Diaconis, and Rice
University), sample size, and distribution type. Three measures are utilized:
the average distance between empirical and theoretical histograms, the level of
recognition by an expert judge, and the accuracy index, which is composed of the
two aforementioned measures. Mean comparisons are conducted with aligned rank
transformation analysis of variance for three fixed-effects factors: sample
size (20, 35, 50, 100, 200, 500, and 1000), distribution type (10 types), and
empirical ru</span><span style=\"font-family:Verdana;\">le to determine the number of
bins (6 rules). From the accuracy index, Rice¡¯s</span><span style=\"font-family:Verdana;\"> rule improves with
increasing sample size and is independent of distribution type. It outperforms
the Friedman-Diaconis rule but falls short of Scott¡¯s rule, except with the
arcsine distribution. Its profile of means resembles the square root rule
concerning distributions and Doane¡¯s rule concerning sample sizes. These
profiles differ from those of the Scott and Friedman-Diaconis rules, which
resemble each other. Among the seven rules, Scott¡¯s rule stands out in terms of
accuracy, except for the arcsine distribution, and the square root rule is the
least accurate.
