A sixth-grade class has 20 total students, while the entire middle school has 1,000 students. A census is taken of the entire school’s population to see on which day of the week every student was born. Theoretically, 14.3%, or 1/7 of the students should have been born on each day. The table here shows that the results for the entire school are closer to this prediction than the results for the sixth-grade class are. What is a good explanation for this?

Question

A) The sixth-graders were all born during the same year and that year was probably an unusual, aberrant year.
B) The data for the entire school is more statistically meaningful because it is drawn from a much larger population.
C) Sixth-graders are younger than the rest of the middle school and more likely to have made errors in their data collection.
D) The data for the entire school reflects students from different grades, while the data for the sixth-grade class is only for sixth-graders.
