This survey, I think most of it is accurate, but there are different reasons and factors that will affect the results of this data. Not all the students in marryatville high have done this survey, and one of the reasons that influence this survey is that many students do sports for more than 100 minutes or more, but if some factors prevent students from doing sports, such as one day, their feet are injured and they can't do sports, it will affect the results of this data. Another factor is that the eighth grade students are only a part of the school. Many students above the age have not done the survey. If too many people have done the survey, there will be many decimals such as the average, and there will be deviations in the calculation.
