Secondly, the concept of data analysis is one of the most important mathematical qualities that students should cultivate in mathematics courses in compulsory education, and it is also an important aspect to promote students' development. In the previous statistics teaching, many of our teachers only regarded statistics as calculation and drawing, ignoring the important position of data analysis in statistics and probability teaching. In fact, data analysis plays an important role in promoting students' development. First of all, through statistics teaching, students' data consciousness can be cultivated; Secondly, through data analysis, students can extract relevant information and choose different methods according to different backgrounds, thus cultivating students' thinking flexibility; Thirdly, in data analysis, students can experience the concepts of randomness and regularity.
Thirdly, the concept of data analysis essentially embodies the basic idea of mathematics.
Fourthly, the concept of data analysis is one of the goals of mathematics curriculum and mathematics classroom teaching.
