Best Of The Best Info About How To Check The Normality Of The Data
How to test for normality in python (4 methods) many statistical tests make the assumption that datasets are normally distributed.
How to check the normality of the data. Which similar to the observation we got from (a) and hence we can say. Click continue, and then click ok. Click the plots button, and tick the normality plots with tests option.
