As you can see in my example, the axis scale does not match the data. The first improvement is the adjustment of the X axis to the data you present on the chart. Formatting an ogive chartĪt the moment, the ogive graph is ready, but you can think about further improving your graph. At first glance, you can see that the greatest increase occurred between 35 and 50. ![]() You can clearly see the value line that grows as the data ranges increase. We have created an ogive chart that looks like this: Select insert (1), scatter chart (2), and scatter chart with marker (3). The important thing is that the plot should contain both a point and a line. Ogive charts are usually scatter charts, but you can also choose to use a line chart. Having calculated the cumulative frequency of your data, you can start creating a cumulative chart. Highlight all of the rows in terms of both ages and cumulative frequency. Put 0 under the cumulative frequency (1), and choose a number that rhymes with the ages under ages (2). Note: Follow this step on the rest, by typing =SUM(B6: B4 beside 50, =SUM(B7:B4) beside 65, =SUM(B8:B4) beside 80, and =SUM(B9:B4) beside 95.Ĭhoose two cells under ages and cumulative frequency, right-click on them (1), and choose insert (2).Ĭhoose to shift cells down (1), and press OK (2). Remember that the task of the ogive chart is to show the sum of the accumulated data? In an empty column, write Cumulative Frequency and proceed to calculate the cumulative sum in column D below.Ĭlick under the Cumulative Frequency, and type =B4, which is the value under Frequency in column B.Ĭlick under the result from the previous result (1) and type =B5+B4.

Write ages on an empty column (1), and write the last numbers in the ages (2). It is all the more acceptable when the data values in these ranges are small. It is allowed that the first and last bins have a different width. Only the first compartment is of a different width. In my example, I decided to create age brackets 15 years wide. Actually, it is from the point of view of the cumulative sum graph, so that they are of equal width. ![]() If possible, try to keep the data intervals of the same size. The most difficult thing to do is to define the data ranges so that they do not disturb the frequency graph. When creating an ogive chart, you are faced with a difficult task. ![]() When inserting an Ogive (Cumulative Frequency) chart, the first thing you need is data like this:Īs you can see in the picture above, the key step is to properly prepare the data table. Therefore, the cumulative frequency plot is always an ascending line that grows by leaps and bounds as you cross data boundaries. An ogive plot allows you to show the cumulative frequency of data values.
