Draw Frequency Polygon through App

Lower limit of first class:

Class width/class size: Lower limit of second class:

Frequencies separated by commas:

How many times the length of side of a smallest square need be taken as unit along X axis? Along X axis, side of each smallest square has length of how many units?

How many times the length of side of a smallest square need be taken as unit along Y axis? Along y axis, side of each smallest square has length of how many units?

Enter a value here to re-height your graph. If you enter 2 replacing previous value of 1, the height will be doubled. The same applies for values less than 1.

Type of class interval:

Coordinates of points on the polygon

Area below the polygon

Frequency distribution table

You want the x-axis labels:

Show description of graph

What sort of graph do you wish to display?

First and last line segments are to appear

Frequency distribution table to draw frequency polygon:

N.B. 1. If you change the value/selection in any field (except for the first one), you will immediately see the desired changes in the graph and graph description. If for some reason you do not see it, click/tap on the green 'Full Solution' button or the graph itself.

2. If the class-width is not a multiple of 5, you can't possibly change the x-axis scalings, by pressing any button. They are fixed for such values of class-width. FYI,
Class-width = Lower limit of 2nd class - Lower limit of 1st class
