bar graphs often comes from the fact that they look very similar (they are both bar charts after all), and they are both used to represent non-continuous data. In a bar graph, however, each bar's height can represent any quantity, and the x-axis can be any field we want, not necessarily a range or category. Such a subset is the compilation of all bar charts in which we have the number of events in a particular range/category plotted in the y-axis, leaving the x-axis to organize said ranges. a bar chart, we need to look at histograms as a small subset of all possible bar charts.

Given that you already know how to make a histogram, and that we've already gone through the histogram definition together, it should not surprise you to find out that a histogram is a bar chart - a special type of bar chart. So, what are the differences/similarities between a histogram vs. So far, we've mentioned histograms and bar graphs almost interchangeably, and this leads us to the direct comparison of histogram vs. One of the most important things that makes a histogram what it is is the fact that the x-values are not continuous (even if they could be in the data), but they are discretized by grouping them into bins that represent a specific range of x-values. Most commonly, the x-axis is represented by numbers (or some quality that can be ordered). In a histogram, the height of each bar in the chart represents the number of times such an event happened, while the x-axis tells us what that event is. Now we have answered the first question, "What is a histogram?", but we don't yet know what makes a histogram look like one. This is ideal when we can assume each even to be independent of each other (like when rolling dice or during a lottery draw).

Coming back to our histogram example of the dice roll, a histogram tells us how many times each number appeared, but it doesn't tell us anything about when a roll happened or which number came before and after. bar charts, and how we can use histograms to understand distributions like the bell curve and more.Ī histogram is a way to represent data by the frequency with which an event occurs, rather than the moment they happen.

So let's dive a bit deeper into the histogram definition, how to compare histograms vs. However, by now you probably have more questions than answers, and that has to change. This can be very useful to analyze patterns and to make predictions, as we will see later. If we had a huge amount of tests (infinite to be pedantically precise), the results would reproduce a probability distribution. In this example we have plotted the result of several probabilistic tests (rolling dice).
