Histogram Maker
Label your graph, add your numbers, then group them into intervals. Each bar shows how many data values fall in that range.
Graph labels
Frequency means the number of data values in an interval.
Your data
Separate values with commas, spaces, or new lines. Include each measurement, even when values repeat.
Decimals and negative numbers work too. Enter one thousand as 1000.
Enter each exact value and how many times it occurs. Enter individual values here, such as 4.2, rather than interval ranges.

Group into intervals
Intervals (also called bins) have equal widths and continue until all your data are included.

Each interval includes its starting value but stops before its ending value. A value on a shared boundary goes in the bar to its right.
