Tamar surveyed six friends, asking each how many times he or she had ridden in a helicopter. the numbers of times she recorded were 0, 0, 0, 1, 3, and 8.

what is the mean absolute deviation of the number of times? round to the nearest tenth, if needed.

a.
0 times

b.
2 times

c.
2.3 times

d.
2.5 times

actually, i just took the quiz, and it doesn't say "round to the nearest tenths", it says "round to the nearest tenth, IF NEEDED" and so, the answer inst 2.5, its actually 2.3. it only meant you had to round if it got into the hundredths or thousandths, not to literally round to the nearest tenth... if your answer is already in the tenths position. there's your proof...

i did it myself and i got 4.2 (b) hope its right
