Ms. Patel's students are working on summarizing data collected from measurements on a single variable. She asks them to make observations about the following list of the numbers of students in each mathematics class at Franklin Middle School.
16, 20, 21, 18, 28, 29, 22, 21, 26, 28, 22, 19, 25, 22, 28
Which of the following student statements provides evidence of statistically appropriate reasoning about the data?
A. There are two numbers that show up three times in the list, so that means the list has two modes.
B. outliers in the list are 16 and 29 because those are the smallest and largest numbers in the list.
C. The median number of students in a math class is 21 because there are 7 numbers before it and 7 numbers after it in the list you showed us.
D. Since there are 6 numbers in the list that are less than 22 and 6 numbers that are greater than 22, the mean number of students in a math class has to be 22.
