I think the answer is enforce the state’s laws
I believe the answer is: Known-groups paradigm
A study is considered to have Known-groups paradigm if the researchers understand that the measure that they take will discriminate a certain groujp of subjects because of their known behavior.
From the case above Dr. Sheffield create a test to determine whether the subject unable to resist impulses to gamble.
The subjects that he use is <u>a group of ex-gamblers</u> who acknowledge they have a gambling problem (gamblers anonymous) and a group of ex-alcoholic who acknowledge they have drinking problem (AA). We can say with high certainty that dr. Sheffield <u>knew really well that people on GA will have higher scores.</u> He just want to how big is the difference compared to the scores from AA group.
The neolothic era was characterized mostly because this was the first time in human history when people started to grow crops and not rely only on a hunter-gatherer type of organization of communities.
Answer:
Observational study
Explanation:
An observational study is a type of study in which individuals are observed and certain measures are measured but there's no intend to affect the actual outcome. In other words, no treatment is given to the individuals and there's no intervention done by the researcher.
In this example, the study aims to evaluate the percent of adults whose right cerebral hemisphere is larger than the right hemisphere. 20 people come and have their brains scanned. Then, the scan is analyzed to identify which hemisphere is larger.
In this study, we can see how <u>individual's brains were observed and some measures were taken but there was no treatment given to them</u> (the researchers were only interested in knowing which hemisphere was bigger).
Thus, this is an example of observational study.
