Answer:The error of overgeneralizing
Explanation:
-Overgeneralization occurs when someone makes an estimation or conclusion that because of one thing is a particular way then the rest of the same thing is also that way, without enough evidence or research to make such conclusion.

- he only has the evidence or the result that only encompasses the few individuals of the population.
