八月天气情况统计表和统计图

How to draw a weather statistics table is introduced as follows:

1. Use a ruler to draw the table. Generally draw four vertical grids.

2. Then fill in the "date", "weather", "highest temperature" and "lowest temperature" in order.

3. The subsequent horizontal grid will be based on the number of days to be recorded. Generally, several grids will be drawn to record the number of days.

4. The thermometer is hung in a relatively open location outdoors, and the temperature value should be read with a horizontal gaze to reduce reading errors.

5. In the last week, record the temperature values ​​at the same time every day, draw a coordinate system, the horizontal axis repre sents time, the vertical axis repre sents temperature, draw points and connect lines.

For the weather record sheet, you can download the template from the Internet and print it out, or if the teacher requires you to draw it yourself, just use a ruler and a triangle to make the drawing.

Weather forecast (measurement) or meteorological forecast (measurement) is the use of modern science and technology to pre dict the state of the earth's atmosphere at a certain location in the future. Since pre historic times, humans have begun to pre dict the weather to arrange their work and life accordingly (such as agricultural production, military operations, etc.).

Today's weather forecasting mainly uses collecting large amounts of data (temperature, humidity, wind direction and speed, air pre ssure, etc.) and then using current understanding of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of atmospheric processes and because today's science does not finally have a thorough understanding of atmospheric processes, weather forecasts will always have a certain amount of error.

Statistical charts learned in primary school are: bar charts and line charts. Bar charts are divided into: single bar chart and compound bar chart. Line chart is divided into: single line chart and compound line chart.

Characteristics of common statistical charts:

1. Characteristics of bar chart statistical charts: It allows people to see the size of each data at a glance. Easily compare differences between data. Can clearly expre ss the quantity.

2. Characteristics of the sector chart: The area of ​​the sector is used to repre sent the percentage of the part in the whole. Easily display the size of each set of data relative to the total.

3. Characteristics of the line statistical chart: it can display the changing trend of data and reflect the changes in things.
