Frequency Polygon Gcse Maths Steps Examples Worksheet A video revising the techniques and strategies for drawing frequency polygons. (higher & foundation).this video is part of the statistics module in gcse math. Example 1: standard problem. the length l\;cm l cm of 16 16 carrots were measured and recorded into a grouped frequency table. draw a frequency polygon to represent the grouped data. use the axes below. calculate the midpoint of each class interval. the midpoints can be found by adding the lower limit of the class interval to the upper limit of.

Plot the frequency of each class against its mid interval value and connect the points with straight lines. 1 number. 2 algebra. 3 ratio. 4 geometry. 5 probability. 6 statistics. affordable 1:1 tutoring from the comfort of your home. tutors are matched to your specific learning needs. Unless one of the frequencies is 0 do not join the frequency polygon to the x axis, and do not join the first point to the last one; the result is not actually a polygon but more of an open one that ‘floats’ in mid air! you may be asked to draw a frequency polygon and or use it to make comments and compare data. To 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).

On the grid, draw a frequency polygon to show this information. (total 2 marks) q4. kevin and joe each manage a shop that sells cds. kevins shop is in the high street ’ and joe’s is in the retail park. they want to compare the sales of cds in each of their shops for the first 100 days of the year. edexcel maths gcse frequency polygons (fh). Example 2: interpreting frequency polygons. the following frequency polygon shows the heights of people two different classes in a school. compare the heights of the people in the two classes. [3 marks] first, find an estimate of the range of the two classes: class a: 210 150=60. class b: 190 150=40. for class b, there is a point that.
