Less Than Cumulative Frequency Polygon. This video explain how to construct a less than cumulative frequency distribution. Mark the cumulative frequency on the y-axis. Less-than-cumulative frequency polygon 22 20 18 16 14 Frequency 6 4 2 0 -15 45 105 16 5 285 225 Length 345 405 O A. Increasing cumulative frequencies are also called frequencies less than whereas those that decrease increasingly are called greater than frequencies.
Mark the cumulative frequency on the y-axis. Plot the points xy using upper limits x and their corresponding Cumulative frequency y Join the points by a smooth freehand curve. Increasing cumulative frequencies are also called frequencies less than whereas those that decrease increasingly are called greater than frequencies. It indicates the total number of values less than or equal to the upper limit of that. Draw a cumulative frequency polygon for the following f Draw a cumulative frequency polygon for the following frequency distribution by less than method. Lower quartile 00 15 0 16 0 195 183 hours.
The cumulative frequency is denoted by CF and for a class interval it is obtained by adding the frequency of all the preceding classes including that class.
Less than ogive method. 165 first quartile 225 O D. There are two kinds of cumulative frequencies namely cumulative frequencies which are increasing and decreasing. Increasing cumulative frequencies are also called frequencies less than whereas those that decrease increasingly are called greater than frequencies. The cumulative frequency is denoted by CF and for a class interval it is obtained by adding the frequency of all the preceding classes including that class. To construct a cumulative frequency polygon and an ogive by less than method we use the following algorithm.
