lol 11 years ago and this is still helping us. Our teacher randomly came up with the assumption that we should be doing statistics because "maths was just simply too easy". So now 1 month before my exam for stats i have to go through the whole thing, Which im almost completed with it. Anyways this was a banger :P
So that's how you find outliers, I knew it couldn't just be guessing which one looks a bit off, phew! You saved my grade, my teacher just wouldn't tell me of any formula and said use logic for it all...
Hi, thanks for the uploads! can you confirm whether you made an error when calculating the outliers upper and lower, as i made it out to be lower outlier = Q1 (12) - 1.5 (19-12= 7) so = 1.5 .... upper quartile = Q3 (19) + 1.5 (19-12=7) so = 29.5 Have i done something wrong? please advise :)
Thank you so much, you just taught me this better in 13 minutes and 57 seconds, than my teachers have in 3 hours ;u;'' you are a life-saver, thanks a bunch ^^ TTuTT;; :'D
Are the outliers really 4 and 26.5 because every time I enter it in my calculator I get 1.5 and 19.5. If that is wrong please someone take the time to explain that to me. Thank you!
Question, what does the left and right skews tell us about data ? Same for if the data is symmetrical ? Also what if the median line is pushed to the right, and the right whisker is also longer ? What if median is pushed right or left but the whiskers are equal in length ? What kind of skews would these be at the point ?
with the correct values for the upper and lower outliers; (29.5 and 1.5) what would the new box and whisker diagram showing the outliers look like? Thank you
Hi,what if the boxes are symmetrical but the whiskers tend to be longer on the right side? Do I say it's positively skewed or symmetrical? Actually, when determining skewness, should we look at the box more or the whiskers? Thanks so much!
I was studying in your site and i would like to know if the box and whisker plots can be drawn in any part of the graph such as at the top or bottom of the graph.
thank you sir for this video..but when I am doing boxplot in spss 26is coming as an outlier....y so?? can you do a video with the same data points in spss...plz sir
ExamSolutions I love your videos, they have helped me so much. However, I'd like to point out the Upper inner fence, or Second Outlier if you will is also inaccurate. Even if you plugged it in the calculator straight, it's 29.5 not 26.5. I don't think it affected the results, but yeah.
+Jack Kelsey :Are you studying statistics? If you need any help on statistics. just let me know, as i am a statistics tutor, and teach statistics. That is completely free of cost.
The median is calculated by find the middle value. In this case there are two values in the middle, 15 and 17. The median = (15 + 17) / 2 = 16. not 15...
oh my heavens I swear this contributor is a life saver I would reccomend this to anybody who takes pure mathematics as a subject

i think there are some mistakes...if i'm not mistaken Q1 -1.5(IQR) =1.5
and Q3+1.5(IQR)=29.5
I made an annotation for this but it is not that clear
Thanks, box and whisker plots just never went through my head. This should definitely help me with my stats test tomorrow.
You should always have some form of scale parallel to the box plot, whether it be vertical or horizontal.
Thank you! You are God's gift when it comes to Maths revision.
Why do I think Jarvis is helping me study Statistics? 🤔 Very good video. It helped me a lot. 👍🏼
So that's how you find outliers, I knew it couldn't just be guessing which one looks a bit off, phew! You saved my grade, my teacher just wouldn't tell me of any formula and said use logic for it all...
very helpful. Thanks... hopefully I can do this on my test since I understand now
+Rachelle Marcial Good luck
learned more from this video than hours in school, thanks
Kickass video!!, had no clue about box plots and it sent me in circles as I have an exam tomorrow but this helps me largely, thank you 😄
Best wishes for tomorrow.

i understood it so perfectly. thanks soooooooo much

you are a life-saver, thanks a bunch ^^ TTuTT;;
:'D
Thank u soooo much.... This is definitely going to help me in the tests 😁😁😁
Good luck

You are right
Thank you very much sir
That is crystal clear 👍👍
Thank you, I am pleased you found it helpful.
@thewreckedup Thanks - I look forward to that
Thank you so much! This totally helped.
This was remade and a new version is on my website.
very good explanation. keep doing such nice videos
Thanks

Thnx u helped alot....
That helped a lot, thank you!

You may well have annotations switched off on the settings on UA-cam.
thank you, helped me alot
Thanks a lot!
thank you sir for this video..but when I am doing boxplot in spss 26is coming as an outlier....y so?? can you do a video with the same data points in spss...plz sir
and outliers are 1.5 and 29.5 right
Do you mean vertical or horizontal. If so, yes.
Thank you.... very helpful
Sandya Shah You're welcome
thank you, where do i find these annotations?
Cool, another life saved.
Yes and thank you sir.
Great video, but the Upper outlier is 29.5 , and the lower is 1.5 I think
Good luck
Thanks alot
What grade would this be for like what grade do u guys learn it in?
mean < median => negative skew
mean > median => positive skew

Hi There was an annotation added sometime ago which you may have missed on the video or you are using an IOS device which does not show them.
I saw the annotation for the 1.5, but not the 29.5
Thanks for the vid, how do you know hoe long vetically the lines have to be
+Jack Kelsey : There is no limit for the length of vertical lines. You can make them as big as you want.
Oh thanks
+Jack Kelsey :Are you studying statistics? If you need any help on statistics. just let me know, as i am a statistics tutor, and teach statistics. That is completely free of cost.
sorry but isn't the value for the second outlier 29.5?
really good video thank you
I made an annotation for this but it is not that clear
ah okay thank you
so the EXTREME VALUE is the number up/down from the maximum and minimum numbers?
Yes, the outliers are the extreme values if you like which are values below and above the calculated min and max values.
But it is a very good video!!!
yeah i also go 29.5 ¬_¬ and here i thought i was the only one getting this answer
Nope, it was me. I made an annotation for this but it is not that clear.
The median is calculated by find the middle value. In this case there are two values in the middle, 15 and 17. The median = (15 + 17) / 2 = 16. not 15...
Look at the box not the whiskers.
WHY IS 30 AN OUTLIER
its funny how a level is slowly shifting towards gcse content. How ironic
incorrect outlier numbers
Please see earlier notes on this. The video has been remade.
Cant you tell I got news for you,
So useful, but your voice makes me sleepy :L
