Process and Method

1. Experience the process of collecting, sorting, describing and analyzing data, cultivate statistical abilities, and consciously use statistical ideas to think and solve some simple practical problems;

2. Develop statistical concepts in the process of collecting, processing, and analyzing data;

3. Able to use statistical methods to make scientific and reasonable suggestions for situations that occur in real life.

Important and difficult points in teaching

1. Data acquisition process and processing;

2. Correctly analyze and extract information accurately, determine samples from the collected results, and ensure the breadth and representativeness of the samples;

3. Properly and accurately analyze statistical data and write investigative reports.

1. Collect data

If we collect and analyze the data of the entire second grade of junior high school, the calculation amount of these data will be very large. We can use the statistical method of sample estimation of the population, first extract a sample, and then estimate the overall situation through the study of the sample.

1. Determine the sample

The sample must be representative and extensive.

5 boys and 5 girls were selected from each grade two class in the school to form a sample with a capacity of 40.

2. Determine the method of extracting samples

According to the student number of each class, the 5 boys and 5 girls with the top student numbers in each class are selected.

Practice in class

1. Investigating students' physical health status is generally divided into six steps: __________, ___________, ____________, ____________, ______________, and communication.

2. When describing data, you can generally make _____ statistical charts and _____ statistical charts.

3. Analyzing data generally involves calculating ______, _______, _____, _____, _____, etc. for each group of numbers, and drawing conclusions by analyzing charts and various statistics.

4. (2005·Yichang City, Hubei Province) Three packaging machines A, B, and C packaged tea with a mass of 400 grams at the same time. 10 boxes were randomly selected from their respective packaged teas. The variance of their actual masses was obtained as follows As shown in the table, according to the data in the table, it can be considered that among the three packaging machines, the _______ packaging machine has the most stable packaging quality.
