Concept Introduction

The raw information obtained from the population of interest is referred to as data in statistics. The collection and validity of this data are dependent on various factors.

Explanation

In the given scenario, as the researchers used various age groups in their samples, such as school-aged children and young adults, the results of the two samples may differ.
