Resolved: Choosing the size of binwidth

Question

Hello,

How would one choose a good binwidth for histogram? What type of problems would a high binwidth be just right or too much?

Thanks,
Carl

Hi Carl,
thanks for reaching out! That's a great question, and choosing the right binwidth for a histogram can be a challenge. There are a couple of approaches to choosing the right size, depending on the sample size for example. Sadly, there is no one correct answer or approach, and most of the time we have to rely on our experience and fit the binwidth according to the data distribution.
You can check out this lesson on choosing the right bin size from our data visualization course:

Let me know if you have any other questions or suggestions on the topic.

Best,
