If the number of data is even then this rule does not apply. In that case for finding the 2nd quartile is to arrange them in ascending order and then the median (middle number for odd number of data, average of the middle numbers for even numbers of data) is the 2nd quartile. Divide the ordered data in two groups, and then median of the 1st group is 1st quartile, median of the 2nd group is 3rd quartile. Example 1 : Ordered data 2,2,3,4,5,5,6,7,7,8,9,9 . total number is 12 (even). median of this data set is (5+6)/2 = 5.5 which is the 2nd quartile. Dividing the data into 2 groups we get 1st group 2,2,3,4,5,5. Median is (3+4)/2 = 3.5 which is the 1st quartile and 2nd group 6,7,7,8,9,9 . Median is (7+8)/2 = 7.5 which is the 3rd quartile. Example 2: Ordered data 2,2,3,4,5,5,6,7,7,8,9,9,11,15 .......... 2nd quartile = (6+7)/2 = 6.5 1st group 2,2,3,4,5,5,6............Median or 1st quartile = 4 2nd group 7,7,8,9,9,11,15...........Median or 3rd quartile = 9
Dude, this literally is the _only_ CZcams video you have made. You realize that you are great at math and can make more. You should, it would really benifit to other people out there who need help in math.
At first I did not understand and then I sow this video and it still did not halp me but then I ask my teacher and she helped me understand ot I did not understand a word he said!!!!
You honestly explained it better than the University prof I have this year.
this guy my be in college 😮😮
You bet, he explains better than a lot ones!

Thx!
thanks much
THANK YOU 💖
thank u so much. such a helpful comment.
You taught me this topic in one minute. My teacher spent an entire class and made me even more confused. Thank you!
Straight and to the point. Thanks man.

This was for a grade.
yall can set the playback speed to 0.75 for a much understandable speed. Great explanation, thank you!!
Yeah i don't know about anyone else but this literally did not work at all for me.
Make more of these! I learnt more in 1 minute, then I did in an hour-long class.
Explained so perfectly in under a minute. Thanks
Fastest lesson of my entire life 💀
What the heck!!!!! not even about to watch it again
People take this at university and I'm taking this at school... there's a simpler formula I think but I forgot it so imma open the textbook again.
THANK YOU SO MUCH CONNOR !!!!!
I LOVE YOU !!!!
Thanks for the quick and straight to the point explanation.
Man now eminem’s gonna diss you
Huh... How do we get 1/4,1/2,3/4 and how do you get the answer 3,5, and 7....
I’m @ middle school and we use waaaaaayy bigger numbers, and it’s a bit hard to understand this whole thing since you use small numbers.
Yea that’s so true!
This works if it's an odd set of group data, What about an even set ?
gotta give u props man...
What happens if the quartile of n have decimals
I do not get it at all
THAAAAAAAANK YOUUUUUUUU! SOOOOOOO MUUUUUUUUCH!
what is the reason for adding 1 to the total number of observations in the formula?
Maybe a little bit slower maybe? It was kind of hard to understand.
you can always rewatch lol
I really appreciate you thanks much you made it so easy to understand
Umm.....this is STILL confusing
love it, just pay attention to the writing .
You earnt my sub
this is so fast but I learned how to get the first, second, third quartile easier and faster than my math teacher😂
thank you btw!!!
Thank soo much ,ahhh you really explain it bette
great Thanks
Where he get 11?
you are too fast
thank you
talking wayyyyy to fast
Thank you
Whaaatt
Wtf I am 15 years old ... and our Math teacher 👨🏫 learns statistics with us...
At first I did not understand and then I sow this video and it still did not halp me but then I ask my teacher and she helped me understand ot I did not understand a word he said!!!!
Where u got 11 from
11 is the total number of data in this question, which is represented by n
i love you.
That was too ez
Conor mcgregor
What happens if the 1/4 of the n is with decimals
Thanku man
One vid
You said it way to fast, dislike
