Solved Construct Frequency Distribution And Frequency Polygon Of The The frequency polygon is shown in the following figure steps: (i) drawing a histogram for the given data. (ii) marking the mid point at the top of each rectangle of the histogram drawn. (iii) also, marking mid point of the immediately lower class interval and mid point of the immediately higher class interval. Frequency polygons are graphical tools used in statistics to represent the distribution of data points. they are essentially line graphs that plot class frequencies against class midpoints, making them very similar to histograms but offering a clearer visual comparison between multiple datasets.

To draw frequency polygons, first we need to draw histogram and then follow the below steps: step 2 mark the mid value of each interval on the horizontal axes. step 3 mark the frequency of the class on the vertical axes. step 5 connect these points using the line segment. step 6 the obtained representation is a frequency polygon. Frequency polygon can be constructed in two ways: (i) using histogram. (ii) without using histogram. 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. step 3 :. To construct a frequency polygon without a histogram we first find the classmark by using the formula classmark = (upper limit lower limit) 2. and we will find the cumulative frequency of each class interval as well by adding the next frequency and previous frequency together.

(ii) without using histogram. 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. step 3 :.

Frequency polygons are used to display a set of data and show the frequency distribution over a continuous scale. to construct a frequency polygon, you need to know the value for the frequency of each group. To construct a histogram, first decide how many bars or intervals, also called classes, represent the data. many histograms consist of five to 15 bars or classes for clarity. the number of bars needs to be chosen. choose a starting point for the first interval to be less than the smallest data value. Frequency polygons are also a good choice for displaying cumulative frequency distributions. to create a frequency polygon, start just as for histograms, by choosing a class interval. then draw an x x axis representing the values of the scores in your data. A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin. the heights of the points represent the frequencies. a frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.
