Answer: A conclusion drawn from a study is considered to be an observation or an inference based on the data collected. In this case, the dentist conducted a survey to determine whether a certain brand of mouthwash improves gum health more than others. The conclusion drawn from the survey results is that the brand of mouthwash in question does improve gum health more than other brands.
It is important to note that this conclusion is based on the sample of patients that were surveyed. A sample is a subset of a population that is used to represent the characteristics of the entire population. In this instance, the sample of patients surveyed may not be representative of the entire population of people who use mouthwash.
