Introduction to Histograms
Introduction to Histograms
What you’ll learn to do: Describe the distribution of quantitative data using a histogram.
![This is a sample histogram, it has bars between -3 and 3 at 1/2 a unit interval ranging with a height of 0 to a little over 25.](https://pressbooks.cuny.edu/app/uploads/sites/126/2022/11/2000px-Histogram_example.svg_.png)
When presented with large data sets, the dotplot is sometimes cumbersome to put together. In addition, it may not be the cleanest way to present the data. For large datasets, a histogram can represent the numerous data points more simply as bars instead of an immense amount of data points in a dotplot. Similar to the dotplot, a histogram is useful in displaying the distribution (aka shape) of the data.
