Question

Mean or median which is better for na substitution

Answer 1

Answer:

hey mate!

I'm doing a project that involves replacing missing values in a set of data (first time doing this). This involves using two methods replacement by mean and replacement by median to fill in the missing values. There is not a lot of difference between the results of the minimum, median, maximum, mean and standard deviation of the data using both methods and I was wondering which method is better and how can I make a decision to which one is better using the results produced?
