Cumulative Frequency Curve. Cumulative frequency is the running total of the frequencies. This example shows how to make a cumulative frequency chart.
A cumulative frequency graph shows the total number of values that fall below the upper boundary of each variable. Dec 03 2020 What is Cumulative Frequency Curve or the Ogive in Statistics First we prepare the cumulative frequency table then the cumulative frequencies are plotted against the upper or lower limits of the corresponding class intervals. It is also known as ogive and it is the most efficient way to represent data.
The video has two sections the first helps you to see how to calculate the modal class interval and the estimated mean average from a set of data presented.
A cumulative frequency graph shows the total number of values that fall below the upper boundary of each variable. A cumulative frequency diagram is drawn by plotting the upper class boundary with the cumulative frequency. The upper class boundaries for this table are 35 40 45 50 and 55. There are two types of cumulative frequencies a less than b greater than.
