Find the percentile rank of 41.
Data Set : 23, 54, 32, 34, 45, 41, 47, 38, 28, 71, 36, 19, 26,
31
Solution:
Arranging Observations in the ascending order, We get :
19,23,26,28,31,32,34,36,38,41,45,47,54,71
Here, n=14
P41=(41(n+1)100)th value of the observation
=(41⋅15/100)th value of the observation
=(6.15)th value of the observation
=6th observation +0.15[7th-6th]
=32+0.15[34-32]
=32+0.15(2)
=32+0.3
=32.3
