Of interest is to determine if the employer of the meteorologist is associated with how well they track the storm. A random sample of 10 meteorologists employed by the U.S. National Weather Service was selected; a random sample of 10 meteorologists employed by a local television station within the United States was selected; and a random sample of 10 meteorologists employed in a country other than the United States was selected. Each was asked to predict the path of a named storm, and a score between 0 and 25 was assigned for each prediction. Of interest is to compare the mean score for the three groups of meteorologists. As described, is this an example of a controlled experiment or an observational study? Observational Study Experiment
