Frequency Polygon Graph Class 9. Let us discuss how to represent a frequency polygon. We plot the ordered pairs 5 3 15 9 25 17 35 12 and 45 9 and join the points by line segments and obtain the frequency polygon of section A.
We provide step by step Solutions of Exercise lesson-16 Mean Median of Ungroup Data And Frequency Polygon Statistics for ICSE Class-9 RS Aggarwal Mathematics. Frequency Polygon The frequencies of the classes are plotted by dots against the mid-points of each class. To construct a frequency polygon first examine the data and decide on the number of intervals or class intervals to use on the x-axis and y-axis.

Aug 11 2016 Frequency polygons are a visually substantial method of representing quantitative data and its frequencies. Use the correct information from the grouped frequency distribution to construct your graphs Pay. Let us discuss how to represent a frequency polygon. To construct a frequency polygon first examine the data and decide on the number of intervals and resulting interval size for both the x-axis and y-axis.
