how 6.25 becomes 7 when rounded up....it was supposed to be remain 6 since after decimal it was 2 lower than 5 which is still the yardstick for elevate the number before decimal.... please explain and do correct me....With regards
It does not need to be a number that is in the data set. The 20th percentile just means that 20% of the data is at that point or lower, and 80% is at that point or higher. It makes no difference if a something from the data is at that point itself.
Of all the videos I searched on percentile scores, this one nailed it! Thank you! I'm a teacher in whacky Cali studying for what's called the CBEST test. Thanks again!
Say there are 8 test grades. 90th percentile would be 8th position(as .9*8 =7.2). That wouldn't make sense because above 90th percentile, we can't find the value
result will be 24.75th value... it is not whole no so 25th value will be taken which is 105...how we can take 105 as 99th percentile bcz 100% values are below this
hello madam , I don't agree with you on the 25th percentle as 75.The correct answer for 25th percentile should be 72. soln 25/100(n+1) 25/100(25+1) 25/100(26) 0.25(26) 6.5 6.5.....6th number and 7th number which is 69+75/2 144/2 72
I'm no longer scared to take statistics. I will continue watching your videos you're an awesome teacher!
Thanks for your teachings. I was really happy listening to your teachings. May God bless you abundantly.
if i had a teacher liker her...i would be statician LOL..

It always has to be the next position in this case, meaning that it should always be rounded up, even if the decimal is lower than .5
thanks alot madam
Thank you teacher.
90 is what percentile in the given the data
Thank you very much.
THANK YOU THANK YOU THANK YOU!!!!!
Thank you Maam..
how to find the pecentile rank of the same scores
thank you!!!!!!!!
Where the K(n+1)\100
68 isn't on the plot. 69 is the 20th percentile.
It does not need to be a number that is in the data set. The 20th percentile just means that 20% of the data is at that point or lower, and 80% is at that point or higher. It makes no difference if a something from the data is at that point itself.
You can get a median that isn't on the plot by taking average. No problems
