After measuring the foot size of 15 of his biology classmates, Laquon finds the average value and claims that it is
the average foot size of all 1,200 students in his high school.
What is most likely a problem with Laquon's conclusion?
He should have found the mode instead of the average.
He should have used shoe size instead of measuring feet.
The amount of data he collected was inadequate.
The data he collected was measured incorrectly.
