Question

\Researchers measured the sugared-beverage consumption and obesity of the same children for two years. They found that when these children added one sugared drink a day to their diet, their risk of obesity increased 60%. Which quasi-experimental design did they use

Answer 1

Longitudinal design

Step-by-step explanation:

There are different types of quasi experimental design in research & experimental psychology.

However, in this case the answer will be longitudinal research design because the same children were studied for 2 years. And this corresponds to longitudinal design which is a study that is aimed at same individual or same group of people over a period of time.
