When you calculate the box plot using normal distribution parameters, the outliers are outside the outer bracket.
If you split the dataset into 4 equal parts, the bracket will be larger because the outliers are still inside it.
The methodologies are not equal.
This thread is the first time i heard people do the "split dataset into 4 quarters" and using that for box plots.
