如何构建程序以便计算数组中数字的不确定性 [英] How do I construct a program so that it calculates uncertainty of numbers from an array

问题描述

我正在学习python，它变得有趣。我想知道如何计算数组中的不确定性。



这是我从.txt文件加载的2D数组

I am learning python and it is getting interesting. I would like to know how to calculate uncertainty in an array.

This is my 2D array loaded from a .txt file

[[5,5,5] 
 [3,4,5]
 [7,8,9]]

我想要做的是计算行中所有数字的平均值，然后得到该平均值的不确定性。



在我的情况下它将是5 + 3 + 7 = 15/3 = 5然后5 + 4 + 9 = 18/3 = 6等等。然后我需要那些平均数的不确定性，所以5和6的不确定性等等。





非常赞赏。

what i want to do is calculate the average of the of all the numbers in the row, and then have the uncertainty for that average.

in my case it would be 5+3+7 = 15/3 = 5 then 5+4+9 = 18/3 = 6 and so on. then i need the uncertainty of those average numbers so uncertainty of 5 and 6 and so on.


much appreciated.

推荐答案

我不知道这是不是答案，因为我不知道不确定性的公式。



请尝试此处： http://www.wikihow.com/Calculate-Uncertainty [ ^ ] - 约有三分之一的步骤是步骤用于你想要的计算。

"I don't know if that is the answer because i don't know the formula for uncertainty."

So try here: http://www.wikihow.com/Calculate-Uncertainty[^] - about 1/3 of the way down is the steps for the calculation you want.
