Statistics is a very profound knowledge! It is still very useful to be an accountant or something in the future! Junior high school, high school and university have to learn! Primary school study is mainly to lay the foundation for future study!
What is the practical significance of statistics?
Statistics is a branch of applied mathematics, which mainly uses probability theory to establish mathematical models, collect data from observation systems, make quantitative analysis and summary, and then infer and predict, providing basis and reference for relevant decisions. It is widely used in various disciplines, from physics, social sciences to humanities, and even in industry and commerce and information decision-making. Statistics are mainly divided into descriptive statistics and inferential statistics. Given a set of data, statistics can summarize and describe these data. This usage is called descriptive statistics. In addition, the observer establishes a mathematical model in the form of data to explain its randomness and uncertainty, thus inferring the steps and matrices in the research. This usage is called inferential statistic. Both of these usages can be called applied statistics. In addition, there is a subject called mathematical statistics, which is devoted to discussing the theoretical basis behind this subject. English statistics of statistics originated from modern Latin statisticum collegium (Congress) and Italian statista (country or politician). German Statistik, first used by Gottfried Achenwall( 1749), stands for the knowledge of analyzing national data, that is, "studying national science". In the19th century, statistics explored its significance in a wide range of data and materials and was introduced to the English-speaking world by John Sinclair. Statistics is a very old science. It is generally believed that its theoretical research began in Aristotle's time in ancient Greece and has a history of more than 300 years. It originated from the study of social and economic problems. In the development process of more than 2,000 years, statistics has experienced at least three stages of development: city-state politics, political arithmetic and statistical analysis science. The so-called "mathematical statistics" is not a new discipline independent of statistics, to be exact, it is the general name of all the new methods of collecting and analyzing data formed by statistics in the third development stage. Probability theory is the theoretical basis of mathematical statistics, but it belongs to mathematics rather than statistics. There are three stages in the development of statistics. The first stage is called "state affairs", which began when Aristotle in ancient Greece wrote "polis politics" or "polis minutes". He wrote 150 kinds of minutes, including a comparative analysis of the social and economic conditions of each city-state, such as history, administration, science, art, population, resources and wealth, which has the characteristics of social science. The statistical study of "city-state politics" lasted for one or two thousand years, and it was not until the middle of the seventeenth century that it was gradually replaced by the word "political arithmetic" and soon evolved into "statistics". Statistics still retains the word "country". The second stage, called "the art of politics", has no obvious dividing line with the stage of "city-state politics", and there is little difference in essence. Political Arithmetic is characterized by the combination of statistical methods with mathematical calculation and reasoning methods. The way to analyze social and economic problems pays more attention to the application of quantitative analysis methods. 1690, william petty published a book (political arithmetic) as the beginning of this stage. William petty's method of quantifying social and economic phenomena with numbers, weights and scales is an important feature of modern statistics. William. Pei Di (political arithmetic) was evaluated by later scholars as the source of modern statistics, William? Pei Di himself was also evaluated as the father of modern statistics. There are three kinds of figures used by the Pei brothers in the book: the first is the figures obtained from statistical investigation and empirical observation of social and economic phenomena. Due to the limitation of historical conditions, the data obtained in the book through strict statistical investigation are few, and more are figures obtained from experience; The second category is the number calculated by some mathematical method. Its calculation methods can be divided into three types: "(1) a method based on known numbers or quantities and following a specific relationship; (2) the method of calculation by theoretical reasoning of numbers; (3) Calculation method based on average value "; The third category is illustrative numbers used for theoretical reasoning. Pego called this reasoning using numbers and symbols "algebraic algorithm". ......
What is the significance of comprehensive practical activities in primary school mathematics?
"Mathematics Curriculum Standard" clearly points out: Mathematics curriculum "should not only consider the characteristics of mathematics itself, but also follow the psychological laws of students learning mathematics, emphasizing the process of abstracting practical problems into mathematical models and explaining and applying them from students' existing life experience." Practice and comprehensive application will help students comprehensively use the existing knowledge and experience, and solve challenging and comprehensive problems closely related to life experience through independent exploration and cooperative communication, so as to develop students' problem-solving ability, deepen their understanding of "number and algebra", "space and graphics" and "statistics and probability", and realize the connection between various parts. "Therefore, mathematics comprehensive practical activity class is a new curriculum form, which aims at solving a practical mathematical problem and arouses students' mathematical thinking under the guidance of teachers. It is the extension and development of mathematics teaching, and the process of understanding and applying the basic knowledge and skills of mathematics. It takes students' life and practical problems as the carrier and background, students' direct experience and latest information as the main content, and students' independent inquiry and topic research as the basic form. Its main task is to cultivate students' independent thinking and problem-solving ability.
How to treat the combination of mathematical statistics and probability in primary schools, with examples.
In the teaching process, teachers should clearly put forward and explain the significance and importance of the subject content, and also understand what practical problems can be solved by the knowledge they have learned through life examples, so that they can feel that there is mathematics everywhere in their lives, experience the importance of mathematics learning, and stimulate and cultivate correct learning motivation.
