Thank you so much for this, Sir! Just want to clarify that the Percentile Rank formula you provided there in the video, how is it different from this formula PR= cf - (0.5 × f) n × 100 and PR=100 (i-0.5/n)?
Thank you very much Glenn sir! Namaste! I am from India and doing a PhD. I was searching for good guidance in statistics. I am very happy to inform you that your tutorials are helpful to me. I have a query, which testing tool will be good for the data of 2000 respondents? T-score/ Z - score or are there any other options for data analysis? please let me know! waiting for your reply. thank you!
How do we explain the differences between the percentile rank and the percentile? In excel using norm.dist(1.06,0,1,1) gives 0.855 so we expect someone with a z score of 1.06 to be in the top 15% but the percentile rank puts them at 77 percentile.
Sir if z-score lang yung need gawin , ano po yung halaga ng percentile rank sa z-score calculation? And sa percentile rank bakit po need mag minus ng 0.5, ano po yung function niya bakit need minus 0.5 sa percentile rank?
Hi, thanks for asking. This video lecture is all about the comparison of raw scores, percentile rank, and standard scores. In my classes, I don't just ask my students to compute for standard scores, I also ask them to compute for percentile rank. This practice is necessary because national exams like NCAE results are given in percentile rank and not in raw score, likewise, some aptitude tests are given in standard scores and not in raw score. The percentile rank formula used in this video is used for manual computation. It is a derived mathematical formula.
sir may i ask, why my stanine group have more than 9, its up to 14? is it okay to divide it into 3 category, so 7 until 14 count as 3rd/high category? thank you before
Please redo your computation. Make sure your mean, standard deviation, and z-score are all correct before computing the stanine. Stanine should only be from 1 to 9.
Very helpful for a Probability and Stats class assignment that I am working on this week. Thanks so much!
THANK YOU SO MUCH, I have to search for just this video to teach me. You saved me!
You're welcome!

Thank you soo muchhh❤
You're welcome,
Thank you so much sir, this is so helpful to me
You're welcome.
"the mean is always 50"? Do you mean sir that the mean is always the number of entries? Or it's really 50 in all cases?
Hi, thanks for asking. In T-score, yes the mean is always 50.
Hi sir. How to get standard deviation in manual computation ?
Thanks alot, very helpful ✨
Glad it helped.
good morning pls
explain stanine to me.
Thank you so much.
You're welcome!
Why 10 sir, it's that the formula or where that we find it
can you do a vedio on stanine using 9 students and a score of 40
i don't understand the ranking sir.
for a example i have student of 9. and a score of 40. can you pls explain from there

Where is slot 9, highest slot is 8
Hi, thanks for asking. The stanine is based on the z - score. If the z - score is greater than or equal to 1.75, then 9 will appear.
