Less Than Cumulative Frequency. Plot the points xy using upper limits x and their corresponding Cumulative frequency y Join the points by a smooth freehand curve. For drawing less than type curve points 20 41 40 92 60 156 80 194 100 201 are plotted on the graph paper and these are joined by free hand to obtain the less than ogive. In less than cumulative frequency CF is calculated by adding the class frequency and frequencies of all lower classes. It is plotted on the vertical axis in a graph.
The cumulate is started from the lowest to the highest size. Similarly CF of less than 175 is calculated by adding 6 with 23 6 23 29 and so on. It is plotted on the vertical axis in a graph. Plot the points xy using upper limits x and their corresponding Cumulative frequency y Join the points by a smooth freehand curve. In simple Cumulative frequency is the running total of the frequencies. Cumulative frequency graphs are always plotted using the highest value in each group of data.
The cumulate is started from the lowest to the highest size.
Less than curve. Plot the points xy using upper limits x and their corresponding Cumulative frequency y Join the points by a smooth freehand curve. Cumulative frequency distribution curveor ogive of less than type. I To plot the ogive of less than type a convenient scale is chosen the scale on both axes may varyThe upper class limit is represented on the and the cumulative frequency is represented on the. For drawing less than type curve points 20 41 40 92 60 156 80 194 100 201 are plotted on the graph paper and these are joined by free hand to obtain the less than ogive. Increasing cumulative frequencies are also called frequencies less than whereas those that decrease increasingly are called greater than frequencies.
