Histogram Maker
Type a grouped frequency table or paste raw data and get a correctly scaled histogram. Unequal class widths use frequency density, so each bar's area is its frequency.
What you can do
- Frequency density for unequal class widths
- A cumulative frequency curve with the median and quartiles read off
- Raw data sorted into classes of a width you choose
- A working table of widths, densities and running totals
- Estimated mean, median, quartiles and modal class
