mysql score如何进行统计分析

在MySQL中，可以使用聚合函数和GROUP BY子句对成绩（score）进行统计分析。以下是一些常见的统计分析方法：

1. 计算平均分：

SELECT AVG(score) as average_score FROM your_table;

2. 计算最高分和最低分：

SELECT MIN(score) as min_score, MAX(score) as max_score FROM your_table;

3. 计算总分：

SELECT SUM(score) as total_score FROM your_table;

4. 按照分数范围进行分组统计：

SELECT 
    CASE
        WHEN score BETWEEN 0 AND 59 THEN '0-59'
        WHEN score BETWEEN 60 AND 79 THEN '60-79'
        WHEN score BETWEEN 80 AND 99 THEN '80-99'
        ELSE '100'
    END as score_range,
    COUNT(*) as count
FROM your_table
GROUP BY score_range;

5. 按照某个字段（例如：class）进行分组统计：

SELECT class, AVG(score) as average_score, MIN(score) as min_score, MAX(score) as max_score
FROM your_table
GROUP BY class;

请将your_table替换为你的表名，并根据需要调整查询语句。
