Answer:
Mean is 8.
Median is 6
Mode is 12
Step-by-step explanation:
1. mean = sum of students ÷ total number of marks divided in section
= 80÷10 = 8
2. median = middle numbers in all
= 0 2 3 5 5 6 8 12 12 12 15
:- 6 is the middle number, therefore median is 6
3. Mode is the number that occurs the most times
= 0 2 3 5 5 6 8 12 12 12 15
12 is the number that occurs the most number of times,
therefore mode = 12
Hope it helps
