Data Processing

NumPy arrays provide diverse functionalities and tools to manipulate extract meaning from raw data.

Mean and standard deviation

Suppose you are measuring the peak value of current passing through a transformer every two hours, but due to temperature changes, there is a fluctuation in the peak value. In order to get a good representation of the data, we will need to calculate the mean value of all 12 readings. The mathematical formula for the mean is given below:

$\overline{a}=\frac{1}{n}\sum_{i=1}^n{a_i}$ ...
