Order the values: 2 4 4 4 4 4 5 6 6 6 8 8 9 12 13 13 13 13 13 15 There are 20 values. 7 values are less than 6.

4. anonymous

Can you tell me what you think the percentile rank is?

5. anonymous

like the definition ?

6. anonymous

no, the number :)

7. anonymous

would it be 12 ?

8. anonymous

no, 6

9. anonymous

so it would be the median ?

10. anonymous

So what would the percentile rank of 6 be?

11. anonymous

im not sure

12. anonymous

okay :)

13. anonymous

i can give you an example with a different number

14. anonymous

okay

15. anonymous

Percentile rank of 14 is (9/15)(100) = 60 or 60th percentile

16. MrNood

@pinkbubbles why 9/15? 12/20 is more intuitive (I acknowledge it is the same number...)

17. anonymous

Okay! :) @MrNood

ugh im sorry i dont get this at all !

20. anonymous

it's fine! :D

21. anonymous

$\frac{ number of scores below x }{ n }\times100 = percentile rank$ So x is 6 andnumber of scores below 6 is 7

22. anonymous

so 7(6)/n(100)=percentile rank

23. anonymous

$\frac{ 7 }{ 6 }\times100=?$

24. anonymous

Correct! :D

25. anonymous

116.67 ?

26. anonymous

but that isnt one of the choices

27. anonymous

Oops sorry i made a mistake so sorry

28. anonymous

no its fine

29. anonymous

$\frac{ 7 }{ 20 }\times100=$

30. anonymous

so 35 ?

31. anonymous

Right! =)

32. anonymous

Do you understand the formula now?
