How Do You Read Pie or Circle Graphs?

50% Circle Graph

Visually data can help organizations identify trends and make well thought-out decisions. There are a variety of different ways of visually displaying data. Bar graphs, histograms, dot, and plot, scatter plots, line graphs, and circle graphs or pie charts. Which type of display you should use entirely depends on your audience and the goal you are attempting to achieve.

A circle graph, or a pie chart is an easy way to visualize numeric information that represents a percentage of whole. The circle is divided into different segments, and each segment represents a part of the data. A lot of students find it difficult to read a pie chart. A complete pie chart, 360°, represents 100%. If half of the pie chart is filled, it represents 50% of the data. The angles help in determining the exact percentages and quantities from a pie chart.

A pie chart represents the results of a survey of the number and type of vehicles were passing a particular junction. Only the number of buses is known, which was 150. You can easily find the number of motorcycles and cars using the given angles. To find the total percentage of each of the vehicles, you have to divide the angle of the sector with 360° and multiply it by 100.

How Is This Skill Used in The Real World?

Circle graphs are used all over the world to help people understand preferences outcomes in all types of industries. In the business world, they are helpful to understand the things that customers would like to purchase through customers surveys. It also helps these businesses understand what customers like and do not like about their current products of services. The goal is to identify the low hang fruit that they should change to improve their overall customer experience. This technique can also be applied to the medical world. It can help physicians and nurses identify the biggest threats to their patients well being and it can even further identify risks. For example, my orthopedic doctor recently shared a circle graph displaying the majority of injuries suffered by tennis players. Elbow tendonitis (tennis elbow) account for more than half of the injuries. I am a tennis player and he was warning me what to look out for. Needless to say, I make sure to properly rest and massage the tissue around my elbow tendon regularly now.
