Text list, statistical data, statistical pictures and statistical tables are three statistical methods for the second grade of mathematics. That is to say, in the second grade, I will learn such statistical methods. The most common thing is to list the data I collected in words, that is, list the data in rows or columns and fill in the blanks of the data accordingly.

Then there is another way to draw statistical charts. If you draw a statistical chart, you can see line charts, some fan charts and some scale charts. But the second grade only requires students to observe, and students are not allowed to draw. Then the third is statistical table.

Statistics will be simpler. Statistical tables are basically consistent with the method of listing statistical data in words. The statistical table only has a few more rules and regulations, and then it is framed to become a statistical table. So the above are three statistical methods for the second grade of mathematics.
