how to know if a population is normally distributed if it’s not precised and the exercise?
Homework Answers
We have to look into some features of the population, like, if the range of the population is real line (or at least R+ ) , if it is symmetric , if its mean median and mode are all same ( if provided).
Another empirical method is , if we have some data points from the population, put it in the graph, if a bell shaped moderately kurtic figure appears, then it can be said that the population follows normal distribution.
