Answer:
D2 = 24
Step-by-step explanation:
given is a data set as
24, 64, 25, 40, 45, 34, 14, 26, 28, 24, 58, 51
We have to find the second decile for the above
Arranging in ascending order we get
14, 24, 24, 25,26,28, 34, 40, 45, 51, 58, 64
2nd decile is equal to 20th percentile
20th percentile formula entry appearing which sorts 20% below and 80% above.
i.e. (20%*(14+1)) = 3rd entry
Thus 20th percentile is24.
D2 = 24
