'N' is randomNormal generated, histogram is therefore PDFnormal. Cumulative weighted classification can be used to identify the PDF that best fit the data set. Is our data set PDFnormal ?.. YES.

To best Engineer collected data: 1. Measuring equipment should be ~ 10 times more accurate than the measured. 2. Make sure the collected data haven't been freaked by else, i.e: raw from collection. Data set not raw from source => recycle.
