Knowledge point 1: Characteristics of compound line statistical charts.

The compound line statistical chart can not only see the quantity and the increase and decrease of the quantity, but also facilitate the comparison of two sets of related data. A line chart consists of: title, time, legend, horizontal axis, vertical axis, points and connected line segments. We can use statistical graphs to solve life problems.

Example 1: The following is Li Xin and Liu Yun training 10 days in advance to participate in the 1-minute rope skipping competition at the school sports meeting. The daily test results are as follows: What statistical chart is appropriate? and draw statistical graphs. Answer the questions based on the statistical graph.

Answer the questions based on the statistical graph.

(1) What is the difference between Li Xin and Liu Yun’s scores on the first day? What about day 10?

(2) What is the changing trend of Li Xin and Liu Yun’s rope skipping results? Who has made greater progress?

(3) Can you predict the results of two people?

(4) What else can you find?

Example 2: The following are the flight time and altitude records of two model aircraft produced by the aircraft model team in one flight.

(1) How many seconds did each of the two planes fly? Which one has a longer flight time?

(2) From the picture, what is the altitude of aircraft A at 10 seconds after takeoff? What about plane B? At how many seconds after takeoff were the two planes at the same altitude? Approximately how many seconds after takeoff will the altitudes of the two planes differ the most?

(3) Talk about the flight status of aircraft B from 15 seconds to 20 seconds after takeoff.

[Analysis] (1) Plane A flew for 40 seconds, and plane B flew for 35 seconds. Plane A has a long flight time.

(2) The height of A is 16 meters and the height of B is 20 meters. The two planes were at the same altitude 15 seconds after takeoff. The altitude difference between the two aircraft was lowest 30 seconds after takeoff.

(3) The flying altitude of aircraft B remains unchanged.
