I'm just impressed that he is writing mirrored
he wrote that normally, he just flipped the video
this isnt grouped data group data would be something like 52.5-55.5 with frequency of 9 and so on
Don't you mean for ungrouped data? :/
Interestingly enough, the 50th precentile is the same as the median. In the first example, being asked to find the percentile value of 5 is simple because it's the median. So, it must be the 50th percentile.
I still don't get it but he's hot so whatever
thx
lol

If you were to calculate the percentile of a 3 in that data set, what would you use for its rank?
What if 1
Very simple explanation. Thank you.
Are we not gonna talk that he's teaching wrong? This is ungrouped data not grouped data.
Yeah even I got confused
Simple enough. Love it!
Still haven't changed the title in 4 years. Winners!
Thanks Woody Harrelson! I never would have guessed you were good at math.
Ian Seegman I choked 😂 he’s hot tho
what is the purpose of 0.5? and how it comes to be subtracting to its number below that specific value and the 0.5? I'm having a hard time to understand some concepts in statistics.
Ronald Joshua Delo my teacher says that's just how it is and I don't get it as well😂😂 btw it's been 2 years since you've commented, do you get it now?
Four years now!
Let's say that it was Ann who scored 5 in this example. Ann's percentile rank is the percent of scores which are less than her score. The tricky part is that we need to include Ann's score in the calculation. It wouldn't be right to count her score as less than itself, or to count it as greater than itself. So we split the difference, and count it as half.
Hi great video, thanks for them. keep the coming please. Please what the materials that you are writing on for it to look like the way it is you and the glass board or so. Please help us with a detail explanation, we need something like that. Thanks
Are you sure it isn’t “i PLUS .5”?
Thank you. Nice explanation
anyone 2020 ?
🤣🤣🤣
Used this formula for a coding challenge, with an employer. Hope this formula provides the answer they are looking for.
Must have worked, I got a follow-up interview. Fingers crossed, let's see how the next round goes.
Thank you, this is very helpful.
Thanks for this vid it really heled me a lot
how am i supposed to focus when the teacher's THIS hot
Thank you so much
He is writing everything mirrored!!!!
What if I only have the SUM of the numbers in the grup and not the numbers themselves ? And on top of that I want to find the percentile for a certain interval of the numbers in the group when I know what the interval IS.
If 10 players are playing, how to rank all of them from 1 to 10 based on the score of each team.
So helpful. Thanks!
thank you! this was helpful
Can you tell me from where that 0.5 comes..
I couldn't understand that
that's constant
thank you
Sir I know a formula for calculate the percentile but ,in this formula doesn't have 0.5 extra addition...
Please clear why u used 0.5 extra additional number...
true limits i guess
How you get the 3.5
wow, some talent he got there, writing those numbers the other way around
how th did he do that? it wasn't mirrored, since if it is, he should've written 11 first instead of 2, but based on how his hand moved it reaaally wasn't
waaa like how the---okay back to the lesson HAHAHA
Thank you sir
Thank You kind sir!
18,21,25,25,31,32,34,40
what is percentile of 34? formula?
81.25
is this grouped data or ungrouped data?
It's ungrouped data old comment now you finally know.
but that data isn't grouped
How do people draw backwards? Just boggles my mind
My teacher gave me another formula... it p=(L+0.5E)(100) divided by N?? it's plus not minus? is my teacher wrong?
What's the purpose of 0.5 ? Where it comes from ??
same answer
what if the result is a decimal? will you round up or round off?
Patricia Moll you round down. I don't get these lessons, but I do know that.
ThX!
ARE WE JUST OVERLOOKING THE FACT THAT THIS MAN IS WRITING ALL THIS SHIT BACKWARDS?!?!?
thanks dad
thats for ungrouped -_-
This video must be his mirror image.
Fact of the matter is that data is ungrouped cuz each score only appeared once.
Hello. How about if its like this
1-10
11-20
21_30
31-40
41_50
And then you're task to find the percentile rank of 41. How are you going to solve this?
Isn't 100x/(i+1) more accurate?
My brain is leaking
Yottifferent me too
What if the #5 in this instance was repeated 7 times, for example?
Vivian Kanchian mulitple 7 and 0.5
thanks!
I did not get the 'i' part. ;_; Someone please explain ;
+Yoong Li "I" stands for the rank of the number. You have seven numbers on the number line, and since he's using 5 in the example, and it's the 4th number on the line, "I" equates to 4. If he was using 11, "I" would then equate to 7.
+Yoong Li the (i) is the rank/place of the number which is in this video it's number 5. so if you count starting from let to right/least to greatest. starting from 2.
From where did 0.5 came??
Lower Class Boundary. I bet he made an ungrouped data video.
@@spacet1m3 but In that example lower class boundary is not 0.5. difference between 2 and 3 is 1 so in that case lcb is 0.5 next term is 3,3 there is no difference between these two so there is no lcb. Next 3 and 5 and difference between 3 and 5 is 2 so in that case class boundary is 1 and so on.
Next time find the difference between grouped data and ungrouped data.
I get it mr.oooooodaym
That is ungrouped data heey
This is not grouped data
pogi mo sir•,• charizz. ty sir muah
this is not grouped.
the formula is + not -
The i-0.5 should be i+0.5 right?
This is kinda helpful to me but my friend still doesn't understand what to do. lol
lol
