学会用Excel如此简单——常用函数的应用(五)
我们先来简单的回顾上一节所关联的内容，上一节我们讲的是函数的编辑技巧，函数的编辑方式一共有两种，一种是对话框编辑模式，还有一种是公示栏编辑模式。对话框编辑模式适用于初学者，方便易懂，但是操作过程繁琐一点，公式栏编辑模式快捷方便，但是要细心编辑，避免参数编辑错误，适用于熟练者。
好的，接下来我们来学习我们常用函数的应用，我们已经通过之前的课程简单的了解到Excel工作表中的函数是有很多种类别的，一上来我们肯定要由浅入深的学习探讨，今天我们就是学习在Excel函数中所划分的一类常用函数。如上图所示，在【公式】下面的【自动求和】（鼠标移动过去就显示如上图所示）下所显示的求和、平均值、计数、最大值、最小值就是我们日常使用中常见的函数了，下面我先简单的介绍一下这些函数的意义。
求和（SUM）：计算单元格区域中所有数值的和；
平均值（AVERAGE）：返回参数的平均值（计算平均值）；
计数（COUNT）：计算包含数字的单元格以及参数列表中数字的个数；
最大值（MAX）：返回一组值中的最大值；
最小值（MIN）：返回一组值中的最小值。
下面小郎老师用实例给大家做一个解释，在上面这个表格中求每一个学生本学期的总成绩、平均成绩、最高成绩、最低成绩以及考试门数（考了几门）。
解决思路：首先我们在遇到问题的时候要先怎么做呢？没错，先看问题，再看要处理的目的，也就是我们所讲的前因后果，题中一共有四个人，求这四个同学每个人的总成绩、平均成绩、最高成绩、最低成绩以及考试门数，我们可以看到最后的温佳悦同学她的数学是缺考的，所以计算她的成绩的时候我们需要注意只有两门。其它的我们只需要套用我们上面所学的常用公式就可以了。
操作步骤：我们可以用我们上一节课所学的内容，函数的编辑技巧第一种就是如上图直接点击【公式】-【自动求和】-【求和】计算我们的总成绩，【平均值】计算我们的平均成绩...以此类推。
最后我们就会得到如上图的结果，我给大家演示的是公式内容，不是答案，再给大家说一下小技巧，像我们的重复动作，计算完第一个同学的成绩后，下面的这几个同学我们只需要选中F4到J4区域，再把鼠标移动到区域右下角的填充柄（也就是变成十字状态），直接向下拖拽就可以完成批量操作，这一步大家也要熟记于心，会在以后的工作学习中帮我们省掉很多的时间。
以上就是本节课的内容，表格给大家放到下面了，不适合手机看，初学者的话在电脑上打开复制到Excel中练习就可以了，任何人的成功都是努力+天赋的结果，道阻且长，大家一起慢慢变强。
