For the data 3, 8, 6, 0, 5, 8, 3, 7-

Correct answer: d i, ii and iii

All three are true: mean 40/8 = 5, median (5 + 6)/2 = 5.5, and 3 and 8 twice each, so two modes.

Why the other options are wrong

• a i and ii: i and ii are true, but iii is true too: 3 and 8 each appear twice.
• b i and iii: i and iii are true, but ii is true too: sorted, (5 + 6)/2 = 5.5.
• c ii and iii: ii and iii are true, but i is true too: the sum is 40 and 40/8 = 5.
