It shows that the radon study suffered from "uncontrolled variables".

Utilizing variables is a vital part of organizing and finishing a test or overview. While the vast majority know about the independent and dependent variables, another sort of variable can change the result of the outcomes. That third variable is the uncontrolled variable, also called as the confounding variable.

An uncontrolled variable refers to the variable in an experiment that can possibly contrarily affect the connection between the independent and dependent variables. This can cause false connections, inappropriate examination of results and inaccurate rejections of a null hypothesis.
