Mean: Add all the numbers up 80+70+20=170.
then count each number you are adding 3 numbers.
then you divide by 3 and 170.
answer is 0.176 and it keeps on going.
Median: put the number in order from least to greasiest
the number in the middle is your answer 70.
hopefully this helped you.

Don't you need to tell us how many of the second half class scored 70 marks?
