Question

当我运行此代码时，我似乎不断下降平均值，并且想知道是否有人有任何建议尝试的一个例子就是做了5个员工，所有人都错过了5天并且平均得到15个，我在做数学错误？再次感谢您的帮助。我发布了完整的代码，以防它不是我试图尽可能整洁的功能，所以很抱歉，如果它有点凌乱，编程不到一个月。

您正在错误地计算平均值。

您有5名员工，每人都错过了5天。

（5 + 5 + 5 + 5 + 5）/ 5 = 5

你的平均值是5。

因此，如果您有5名员工按顺序错过了几天：4,3,2,4,5。然后你的平均值=（4 + 3 + 2 + 4 +5）/ 5 = 3.6

平均值是所有观测值的总和除以观测值的数量。

平均2个功能
