1, statistics and probability is one of the important fields of mathematics learning in compulsory education. The primary school stage includes three themes: data classification, data collection, arrangement and expression, and the possibility of random phenomena. These contents are distributed in three learning periods, from shallow to deep, interrelated, understand the basic knowledge of statistics and probability, understand the process of data analysis, and form data consciousness.
2. Possibility of random phenomena.
Can list random phenomena in life, list all possible results in simple random phenomena, and judge the possibility of simple random phenomena. For some simple problems in real life, we can judge the possibility of random phenomena according to the information provided by the data.
3. Data collection, collation and presentation
We can obtain data from newspapers, magazines, television, internet and other media according to the needs of the problem, or obtain data through other appropriate means. We can organize the data into bar statistics and broken statistics, understand the functions of bar statistics, broken statistics and fan statistics, explain the meaning of statistics, and make simple judgments and predictions according to the results.
Be able to understand the statistical significance of percentage in real situations, solve simple problems related to percentage, form data consciousness and develop application consciousness in the process of understanding and applying statistical charts and percentages.
