For example:

a percentile score of 80 is a score equal to 80 or better than 80% of the scores obtained.

SavvysavzNot sure I've done such a good job of stating it clearly... Does it help in any way ?

WaïtiWaïtiSo you actually say that the a 80-th percentile is all the people who scored 80 or less. For instance, the 2-th percentile is the group of those who scored 1% or 2%? Is there any chance I got it right?

maverick88more.Similary, those who scored 2%.___If you don't mind I would like to add one more thing which has nothing to do with your original question.

Only objects are useful. When referring to people, it is an offending statement which gives a different context altogether.But I understand what you wanted to say. It should be ''you're extremely

helpful''.Regards.

SavvysavzP.S. Yes, I'm sorry (you got right what I meant)

Thanks again!

maverick88Actually I'm not sure what you mean by 'to score 80'. If this is the variable that you are statistically studying and sampling that has this value of 80 (whatever it is) then no, it doesn't quite work like you suggest.

The 80% percentile is the exact value that has 80% of the sampled population below it and 20% of the population above it.

Let's assume

~~for argument's sake~~you study how tall are people in~~say~~Israel. For boys you may find the average height is 1.75 meters. You may also come to the conclusion for instance that the value of~~say~~1.80 meters represents the 80% percentile, meaning that 80% of the boys are less than 1.80 meters tall.Hope this clears it up a bit with the example.

WaïtiI just came across this link: http://water.usgs.gov/waterwatch/percentile.html

Hope that steers clear of all your doubts.
