How to prepare a pie chart
The following instructions explain how to make a pie chart using an example.
- A pie chart is a great way to show how proportions are divided up. We are reminded of this on television every time we vote. In the elections, percentages are converted and then presented as a piece in a round cake, with the whole round cake always making up 100%.
- This is how you should keep it, e.g. B. record the class representative election as a pie chart. You have three candidates in total. The three candidates will split the pie of your pie chart among themselves. The decisive factor is who can collect the most votes cast. That means there are 50 people in your class, so these 50 people can vote, and if everyone votes, 100% of the votes are cast.
- Then it is counted so candidate 1 has only 10 votes, candidate 2 has 15 votes and candidate 3 has the remaining 25 votes. Now you can calculate the percentages of the individual candidates using a simple rule of three.
How to do the conversion
- If you want to know how to make a pie chart, this is where you should pay extra attention. You now have the individual percentages. They are candidate 1 has 20%, candidate 2 has 30% and candidate 3 received 50% of the votes cast by the class.
- Now take a pair of compasses and draw a circle. This circle has 360 degrees, so if you want to create a pie chart, you have to convert the percentages in the circle into degrees. Start very simply with candidate 3, so he has 50% and therefore gets half the cake. So divide your cake in two with a straight line through the middle. In one half you write candidate 3 and write 50% after it.
- The other half, i.e. 180 degrees, you now divide to candidate 2 receives 108 degrees, i.e. 30% of your circle and the remaining 72 degrees or 20% are left for candidate 1. If you've been paying the right attention, you now know how to make a pie chart.
