To create an ogive, first create a scale on both the horizontal and vertical axes that will fit the data. Then plot the points of the class upper class boundary versus the cumulative frequency. Make sure you include the point with the lowest class boundary and the 0 cumulative frequency. Then just connect the dots.

Videolar It's very similar to a histogram, only instead of rectangles, an ogive has a single point marking where the top right of the rectangle would be. It is usually ... |
For drawing such a curve, the frequencies must be expressed as a percentage of the total frequency. Then, such percentages are cumulated and plotted, as in the ... |
3- The Ogive. This type of graph is called the cumulative frequency graph, or ogive. The cumulative frequency is the sum of the frequencies accumulated up to ... |
Cumulative histograms, also known as ogives, are graphs that can be used to determine how many data values lie above or below a particular value in a data set. |
Represent the class boundaries for the histogram or ogive, or the midpoint for the frequency polygon, on the x axis. Plot the points and then draw the bars or ... |
