WebWhat is a histogram? A histogram is a chart that plots the distribution of a numeric variable’s values as a series of bars. Each bar typically covers a range of numeric values called a bin or class; a bar’s height indicates the … A histogram is bell-shaped if it resembles a “bell” curve and has one single peak in the middle of the distribution. The most common real-life example of this type of distribution is the normal distribution. See more A histogram is described as “uniform” if every value in a dataset occurs roughly the same number of times. This type of histogram often looks like a rectangle with no clear peaks. See more A histogram is described as “bimodal” if it has two distinct peaks. We often say that this type of distribution has multiple modes – that is, multiple values occur most frequently in the dataset. Related: What is a Bimodal Distribution? See more A histogram is left skewed if it has a “tail” on the left side of the distribution. Sometimes this type of distribution is also called “negatively” skewed.

WebComputer Science Department at Princeton University WebApr 1, 2011 · Section snippets D2 shape distribution. A D2 (see Fig. 1) histogram is a statistically shape signature of a 3D model [10]. It is produced by computing the distances between points sampled randomly on the surface of a 3D model and allocating them into bins of different distance intervals, which results in a shape distribution of the 3D model.
