Sal has such good handwriting with a mouse. And when I try that, I usually end up writing something even worse than with my left hand.
Thanks for explaining the outliers. I use Minitab in work for statistical analysis and wondered why the box plots put asterisks as outliers but now I know!
The straight lines though!!!
thank you so much! just help me realize what I was doing wrong ... just in time before test!
same tbh (Hope u got a great grade) (0.
hi i love your channel so much
Why 1.5?!
How about finding an outlier in two variable points? I've made the pearson correlation coefficient and one data point was really far away, however, i want to prove that it's an outlier. What formula can I use?
Thanks ...understood the outliers visually and through calculations.
Great explanation. But can you help in representing the outliers using python pandas.
Really helpful. Thanks
very great explanation
Thanke
Thanks a lot..
Thank you im doing this the day before the test
Rohit Nemani its been 11 months, how did the test go?
Yo same
Smeee
thank you
Thanks so Much this helped me alot
Nice video
Great explanation. Thank you
Omg legend!!! Thank you so much!!
Good work
that was actually very Awesome!!!! Thanks Sal!!!!
Who has to watch this video cuz they're doing data stuffs in Math class?
fool-proof! thanx a lot!

Hi Jeff, what would we do to find our Q1 and Q3 if we have an even number of values?
Kelly B find the average of the 2 middle numbers
Probably known by now, but for anyone wondering, you add the two numbers in the middle then divide by two. For example.
3, 3, 7, 9
This would be (3+7)÷2=5
The median is 5
1
tq soooooooooooooooooo much sir for helping us :)
this helps me
What program is Sal using for explaining? Sketchbook?
thats good question !!! ill let u know when i found out!
no

@@toiletpaper3536 Lmao @Sagen Sagita Sal uses a PC with:
Camtasia Recorder ($200*) SmoothDraw3 (Free) Wacom Bamboo Tablet ($80)
After removing outliers, shouldn't the value of Q1,Q2,Q3 be changed?
Came here to ask this too.
im the first like and view!!!!!!!!!!!!!
Nice!!
now Im jealous!!!!!
You will be in Guiness book !!!
GREAT VOICE!
My IQR is greater than my Q1. What do I do???????????
Shouldn't be
watching these amazing nobody every should fail in or complain about statistics ....!
love ❤🎉
YUSSS it was 1 C:
I
1+1=3
1
1+1=11
he kinda sounds like CORPSE
oh no... magic number scare me
I still don't get it -_-
Bruh
Came from math class lol
you legend
You lost. me when you changed the 1.5 to 7.5. I thought the 1.5 was part of the equation. Why isn't it 13 - 1.5 x 5 ??
so so what
I didn't understand anything.....
less big word i can't understand -his kid >-
You never showed what an outlier is smh
