Bar Charts and Histograms are used for two different purposes. Bar charts measure qualities; histograms measure quantities.
Bar charts should be used to explain how much stuff there is in different categories, and categories are qualitative. So, what do I mean by "categories" or "qualtitiave"? I mean things like Toyota cars, Honda cars. "Toyota" is a quality because "Toyota" is not based on a number. (Explained in detail with bar chart below)
Histograms tell how you how much stuff is associated with numeric ranges (more ) . For instance, imagine a class took a quiz, and you wanted to display how many students scored between a 90-100, and a 80-89, 70-79, 60-69. In this case, the you are measure a numeric quantity like 90-100. We call this quantitative data. Read on to better understand the differences in this two types of charts that look similar but are not interchangeable.
When to use bar chartsAnswer:
It's about "quality"
example of a Bar Chart
Bar charts are used to show how much "stuff" different categories have. Imagine, for instance, if you ask all of the students in your grade to choose a favorite color. And 40 chose green, 33 chose orange, 25 chose yellow and 15 chose blue. This is not a situation for a histogram (as you'll see if you read onwards). Instead, you should create a bar chart like the one below
