To find Percentile rank of X =6.5:
4,4,4,5,5,6,6,6,6,7,8,8,9,9,10,11
Total number of observations = 16
Percentile rank formula:
percentie rank = ( L N ) ( 100 )
Of these 16 data values, 9 are less than or equal to the data value 6.5
percentie rank = ( 9 16 ) ( 100 ) percentie rank = ( 0.5625 ) ( 100 ) percentie rank = 56
Therefore, the percentile rank of X =6.5 is 56%
