I'm not entirely sure what is meant by "mathematical term," but histograms (or bar charts) are frequently used in statistics as a visual representation of the distribution of values in a data set. The advantage is that histograms provide a quick visual check that the assumption of normality has been met. There are also statistical tests for normality, but the accuracy of these tests has been questioned. Histograms, on the other hand, allow you to quickly identify not only normality, but also particular patterns or outliers in the data that may be causing a non-normal distribution.

  • another advantage is a it can be useful to identify the distribution of the data
