Marking points
M1 (a) · 1 mark · Sum of all apples and division by 5 shown. (follow-through)
A1 (a) · 1 mark · Mean calculated as 13.2 (follow-through)
B1 (b) · 1 mark · Mode identified as 12
B2 (c) · 1 mark · Median identified as 12
Worked solution
Sum = 12 + 15 + 12 + 18 + 9 = 66
Mean = 66 ÷ 5 = 13.2
Data in order: 9, 12, 12, 15, 18; mode = 12 (occurs twice).
Median is the middle value = 12.
