| Answers Explanation & Hints:
Inferential data are gathered from a sample to make generalizations or predictions about a population. Because a representative sample is used instead of actual data from the entire population – a possible concern is that the particular groups chosen for the study and/or the environment in which a study is carried out, may not accurately reflect characteristics of the larger group. It is important to make sure that the representative sample closely matches the characteristics of the overall population, in order to make accurate analysis from the inferential data set. |
