Question

Kevin scored at the 65th percentile on a test given to 9740 students. How many students scored lower than Kevin?

Answer 1

• kevin's percentile is 65

,

• we will use the formula :

percentie of score x = [(number of data value less than x) /(Total number of data value )* 100]

65 = (number of data value less than x) /9740)* 100

Therefore : (number of data value less than x) =( 65 * 9740/100)

= 6331

• This means that number of student who scored less than 65 / less than Kevins 65 % = 6331,
