The GDP measures the total value of all final goods and services produced in a particular nation in a given year
Explanation:
the GDP (Gross Domestic Product) is the most commonly used parameter when it comes to evaluating a nation's economy, as well as often being connected with the standard of living of the people in that particular nation. This parameter represents the total value of all final goods and services that have been produced by a particular nation in a given year.

Explanation:
The control group in an experiment, is the group that does not receive the treatment that is being tested in that study. Therefore, this group must present different results from the experimental groups that received the treatment that is being tested.
In the experiment shown above, the control group is formed by the ladies who did not receive any dose of alcohol and therefore had a faster reaction time than the individuals who formed the experimental groups (who received alcoholic drinks)
To make the experiment more accurate, Dr. Fitz should have formed all groups with men and women, since he could show whether the effect of alcohol is the same or different in relation to gender.
