Approximate the 75th percentile for these data 10 44 15 23 1
Approximate the 75th percentile for these data: 10, 44, 15, 23, 14, 18, 72, 56.
Solution
Arrange the Given data,
10 , 14 , 15, 18 , 23 , 44, 56 , 72
Divide the sets into Quartiles,
10 , 14 - 1st Quartile,
15,18- 2nd Quartile
23,44- 3rd Quartile,
56,72 - 4th Quartile,
3rd Quartile is 75th Percentile.
it is Halfway betwen 44 and 56
So (44+56)/2=100/2=50
Answer: 75th Percentile = 50
