If line graph focus on tendency, pie chart (pie chart) focuses again on distribution. There’s something that pie chart do better than the other 2 chart types, that is comparison so ratio of different components in an audience, for example: different disciplines in a school, different professions pursued by young people, etc.
As the English name of the pie chart indicates, a pie chart is a pie (pie) divided into different pieces. The comparison in the pie chart will come from the difference in the densities of the pieces. Of course, we’ll have one of the biggest and one of the smallest, along with other pieces in between.
In the pie chart, the expression we use the most is:
A accounts for… % of the total X
Like other lessons, the repeated use of a structure in the lesson should be completely avoided in Task 1 in particular as well as Writing in general. So to avoid repetition we will have to:
- Change word accounting for: fortunately, this word in English has a number of different expressions so we don’t have to change the subject and predicate too much.
- Reverse: instead of starting with object A, we can write “… % of total X .” do activity A“. The “do activity A” part must be flexible, because the object is not always the action.
- “A is the first/two/three most common…” : we can also talk about the order of the pie. This is a good expression because it directly compares the object we are comparing with other objects.
Take a look at the following example:
With Asia Pacific (including former Soviet Asia) in 2000, we can write in three ways:
Asia Pacific (including former Soviet Asia accounting for 54% of the total world population.
54% of the total world population live in Asia Pacific (including Soviet Asia)
Asia Pacific (including former Soviet Asia) is the most densely populated place In the world.
Pie charts are perhaps the easiest to describe in terms of sequence. If you only have 1 pie chart, you can just go from big to small. If you have many pie charts, which are highly likely to show different time periods (usually years), you also go from large to small, but also compare the change in ratio. important while writing.
Let’s take an example of a sample pie chart problem:
This article has 2 pie charts in 2 different years, 1980 and 1990. You just go from big to small:
oil => natural gas => coal => hydroelectric power => nuclear power
- When it comes to oil, please note we don’t just say “oil accounts for the highest proportion…”, we need to mention is the density of oil reduction in the year 1990.
- You don’t need to write much about natural gas, since the data are not much different now at 2 years => Lesson can be learned here: if it is almost unchanged, don’t write in the change, but write in the sense keep stable.
- Coal although the change is small, it is still a noticeable change (5%), and you should comment on this detail.
- Similar to natural gas, hydroelectric power exactly the same at 2 years.
- Although the change in % is quite small compared to other fuels, we must realize one thing about nuclear power That is it double in 1990 => You always have to pay attention if the data increases by how many times compared to the past.
Wish you all good study!
