When you actually use the Excel normal distribution function, you say, norm distribution.

当您实际使用 Excel 正态分布函数时，您会说，正态分布。

The normal distribution function is a continuous probability distribution so it's a continuous curve.

正态分布函数是连续概率分布，因此它是一条连续曲线。

And Excel has a normal distribution function but I actually typed in the formula because I wanted you kind of see what was under the covers for that function that Excel actually has.

Excel 有一个正态分布函数，但我实际上输入了公式，因为我希望你能看到 Excel 实际具有的函数的隐藏内容。
