Parametric data investigation


A oft discussed issue is the presence of parametric parameters in a data .

What are the pre existing conditions which might warn  a researcher of the nature of the data?

Why can't a frequency data  be a parametric data and does it also mean it cannot have a normal distribution no matter the size of the data.



A perpect parametric normal distribution may never exist. All we try and do is to find the best fit, which is theoretically explained.
