Frequently Asked Questions
What is the difference between a histogram and a bar chart?
A histogram shows frequency distribution of continuous data — bars touch each other because the ranges are continuous. A bar chart shows categorical data with gaps between bars.
How many bins should I use?
A good rule of thumb is the square root of your data count, or 5-15 bins. Too few bins hide patterns, too many create noise.
Can I use custom bin ranges?
Yes — you can type any range label you need (e.g., "0-10", "10-20" or custom labels).
When should I use a histogram?
Use histograms to show data distribution — test scores, age distribution, income ranges, response times, or any continuous measurement grouped into ranges.
