Answer:
Arranging the data in ascending order
12,14,15,16,17,18,20,20
here, n=8(which is even no.)
Therefore, median = (n/2th) value + (n/2 +1)th value
_______________________
2
=(8/2)+(8/2+1)
__________
2
= 8/2+10/2
_______
2
= 18/2
___
2
= 9/2
= 4.5
Now, here, 20 is the most repeating digit in this set of data
so, mode = 20
Hence, median is 4.5 and mode is 20
