Characteristics of three statistics in primary school mathematics
1. Advantages of bar chart:?

Not only can you see the specific quantity of each category intuitively, but you can also clearly see the maximum and minimum, which is convenient for comparison.

(1) will collect and sort out data and complete statistical tables.

(2) The drawing of statistical chart will be completed according to the statistical table. (When the number is large or you can't see how much the straight bar represents at a glance, especially remember to mark the number.)

(3) Can read pictures and see basic information from statistical charts.

(4) Analyze the data according to the table presented in the statistical chart. Will make correct and reasonable suggestions and make some simple inferences.

Second, the characteristics of broken line statistical chart:

The broken-line statistical chart can not only see the quantity, but also clearly show the change of the quantity.

Third, the characteristics of the fan chart:

Sector statistics chart uses circles to represent the total amount, and sectors with different sizes to represent the number of each part; The data in the pie chart shows the percentage of each part in the whole, not a specific quantity. Therefore, the fan-shaped statistical chart can clearly show the relationship between the quantity of each part and the total amount.
