Cumulative Relative Frequency Graph. The upper class boundaries for this table are 35 40 45 50 and 55. It looks like an upside down S. The last value will always be equal to the total for all observations. In the graph put the lower limit on the x-axis.
The upper class boundaries for this table are 35 40 45 50 and 55. For instance the first relative frequency of an occurrence is two out of 20 and the second relative frequency is five out of 20. In the graph put the lower limit on the x-axis. It can be easily done using Microsoft Excel. On a graph it can be represented by a cumulative frequency polygon where straight lines join up the points or a cumulative frequency. This article discusses how to read a cumulative frequency graph.
A cumulative frequency diagram is drawn by plotting the upper class boundary with the cumulative frequency.
A Cumulative Frequency Graph is a graph plotted from a cumulative frequency table. The cumulative frequency is the running total of the frequencies. The creation of the cumulative frequency distribution graph involves the following steps. Mark the cumulative frequency on the y-axis. In the graph put the lower limit on the x-axis. For instance the first relative frequency of an occurrence is two out of 20 and the second relative frequency is five out of 20.
