Which of the following data sets would be suitable to determine the total percentage of absences in a school?

Population and statistics includes all members of a defined group, that are being studied. A sample will be a part of that population. So if we wanna know the total percentage of absences in a school, if we just took the sample, we may take a sample of a student who misses a lot of school. But in general, over 98 percent of the students may have perfect cot- perfect attendance, but the one student that we took a sample of or the- a few maybe that we took a sample of may not go to school very often.

So the better dataset to choose would be the mass population. This would give us a better total percentage of the absences in a school than just a sample.
