Normal distribution histogram definition

WebThis statistical parameter quantifies how far the distribution of pixel/voxel values depart from a symmetrical, bell-shaped distribution (i.e., a normal distribution). A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, n…
