Webb12 okt. 2024 · Histograms are appropriate if your data is continuous (i.e., at the interval or ratio level of measurement). Classes are contiguous - you can't miss out a class because it's empty, for example. Classes should have the same width (interval). Classes should encompass the entire distribution of data. WebbTo 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, non-overlapping intervalsof a variable.
