There are many skills in solving mathematical statistics problems in senior high school. Here are some common techniques:

1. Be familiar with the basic steps and methods of solving problems. For some basic and common problems, predecessors have summarized some basic problem-solving ideas and common problem-solving procedures. Generally, as long as you follow these ideas and steps, it is often easy to find the answers to the exercises.

2. Carefully examine the questions. For a specific exercise, the most important part of solving the problem is to examine the problem. The first step of examination is examination, which is a process of obtaining information and thinking. Read the questions slowly, think while reading, pay special attention to the inner meaning of each sentence, and find out the implied conditions.

3. Be good at using probability model. Probability model is a very important part of high school mathematics. Being good at using probability model can help us better understand and solve some practical problems.

4. Be good at using statistical charts. In high school mathematics, statistical chart is also a very important part. Being good at using statistical charts can help us better understand and solve some practical problems.

5. Do more exercise. In high school mathematics, exercises are also a very important part. Doing more exercises can help us better master knowledge points and problem-solving skills.
