What is percentage?
Suppose, there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.
For example 2% means [tex]\frac{2}{100}[/tex]. Here 2 is expressed as a fraction of 100.
Here the concept of percentage has been used
With a grade point average of 3.83, Michelle Robinson graduated above the 93rd percentile of her graduating class.
Let the full grade point be x
His Percentile = [tex]\frac{3.83}{x} \times 100[/tex]
By the problem,
[tex]\frac{3.83}{x}\times 100 = 93\\x = \frac{3.83\times 100}{93}\\x = 4.118[/tex]
Median GPA = [tex]\frac{4.118}{2} =2.059[/tex]
Percentile rank of the student whose GPA was the median GPA = [tex]\frac{2.059}{4.118}\times 100[/tex]
= 50 percentile .
