21 paź 2024 · Just like with a frequency distribution table, some data require the use of intervals when creating histograms. When the range of scores is too large to fit into approximately 20 bars or less, intervals are used instead of scores for creating the x-axis of the histogram. There are two ways the x-axis is commonly displayed when intervals are used.
A bin —sometimes called a class interval—is a way of sorting data in a histogram. It’s very similar to the idea of putting data into categories. What is a bin in statistics: Why not use “Categories” instead of Class Intervals?
What is the correct number of intervals (bins) for histograms? Use the square root of the sample size, e.g., in this case the sample size \(n = 20\) and \(\sqrt{n} = 4.5\), round to 5. Follow Sturges’ rule (to get the suggested number of intervals for a histogram, let \(k\) = the number of intervals, and \(k = 1 + 3.322 \left(\log_{10} n ...

In order to create histogram plots with exact same intervals or 'binwidths' using the Freedman–Diaconis rule either with basic R or ggplot2 package, we can use one of the values of hist() function namely breaks.
