Frequency Polygon Maker

This tool will generate an editable frequency polygon comprising up to three separate distributions (thereby allowing you to compare their shapes). Just enter your scores into the textboxes below, either one value per line or as a comma delimited list, with one distribution per box, and then hit the "Generate" button. The tool will create the frequency polygon, and then give you the chance to edit it.

Before you start, though, a couple of things to take into account: (a) empty spaces - including two or more commas in a row in a comma delimited list - will be treated as if they are a score of zero; and (b) don't include commas within a single integer - e.g., 1,000 - because it will cause the algorithm to split the integer apart.

Note, we also have an Easy Histogram Maker through which you might want to run your data.

Distribution 1
