WebOct 21, 2024 · Following are the steps to drawing a frequency polygon graph using a histogram: Step 1: Draw a histogram for the given data set. For drawing with a histogram, draw rectangular bars against the class intervals with the height (or length) equal to its frequency. Step 2: Join the midpoints of the bars to get the frequency polygons. Examples WebTo draw a frequency polygon we plot the midpoint with each group against the frequency. The midpoint of 0 and 10 is 5. We could work this out by adding 0 and 10, and then dividing by 2: 0 + 10 2 = 5. For the first point we plot (5, 7) The midpoint of 10 and 20 is 15. 10 + 20 2 = 15. The second point is (15,9) d wolf electric bend oregonWebWhen drawing a histogram, the y-axis is labelled ‘frequency density’ or "relative frequency". You must work out the relative frequency before you can draw a histogram. To do this, first decide upon a standard width for the groups. Some of the heights are grouped into 2s (0-2, 2-4, 6-8) and some into 1s (4-5, 5-6). dwolla account types
