WebFrequency Polygon can be constructed in two ways : (i) Using histogram (ii) Without using histogram Construction of Frequency Polygon with Histogram - Steps Step 1 : Obtain the frequency distribution from the given data and draw a histogram. Step 2 : Join the mid points of the tops of adjacent rectangles of the histogram by means of line segments. WebThe relative frequency is equal to the frequency for an observed value of the data divided by the total number of data values in the sample. (Remember, frequency is defined as the number of times an answer occurs.) If: f = frequency n = total number of data values (or the sum of the individual frequencies), and RF = relative frequency, then: canal plus tchat

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 WebWhen 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). WebYou can construct a frequency polygon by joining the midpoints of the tops of the bars.

"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) " - How do you draw a frequency polygon
