- This video covers how to use the "2^k" rule to determine the number of classes for a frequency distribution. Remember when determining the width of your classes to round up to the nearest whole integer. For more videos please visit www.mysecretmat...
You are a Godsend, my teacher threw a book at us and said " your assignments are due on these dates." Without you, I am doomed to fail
man...just...thank you...
Thats a great video
thanks a lot mate
Easy , simple, straight to the point
Good work
Cheers
U
Thank you so much! So useful for my one stats assignment. Wasn't clarified at all, how to get "k"...
Thanks for saving my ass.
Got an exam today😂
Glad I could help! :^D
if we round off 6.4 , it stays as 6 right? no mehh?
you are doing god's work sir
This was very helpful , hands up
isn't the term hands down lol
To find the number of class (n)
m= number of values
N= 1+3.322(log(m)) then round it off
N=1+3.322(log(20))
=5.322≈5
N=1+3.322(log(50))
=6.643≈7
Omg , I was having hard time til I came across your video, so very helpful . Thank you so much !! ❤
thank you ..
you helped me to finish my homework :D...
Where did you bring 5 classes? You did not calculate K? According what you chose 5 classes!
It has 5 rolls of numbers, this makes the classes
Thank you. There are a million videos that show how to find the class width but none on how to find the number of classes.
Thank you very much
Very clear thanks for the post
Thank you a lot. You helped me in my thesis
Thank you 🙏🏾
Thank You. Really Helpful
Thanku sir for clearing 2^k rule
Thank you again you guys are awesome!!!!!!!!!!!!!!!
So helpful!!!!! Very clear and easy to understand!
Thanks!
Thank for this video tutorial 🙂🙏
YOU'RE AMAZING!
I really think this video is great because I could'nt find any other video that showed the 2^k rule so thank you
Thank you, am writing in two hours or so...
Thank you
Thank you So much !!
So helpful
really thank you it was more helpful
Kindly solve this when rangw is 4 and 2 is the interval 5 is the highest and 1 is the lowest posible score
Thanks
Thank you :) Great video!
thanks!
Using Tally makes it easier for first time learner to find how many of the data is in each class
Kindly solve this when rangw is 4 and 2 is the interval 5 is the highest and 1 is the lowest posible score tia
You're amazing in teaching ☺️
interesting rule of thumb for determining the number of classes
Thank you!
*Thank you* 💙
Thank you so much
Help!!
I have 20 data points, the largest number is 43 and the smallest number is 3.
I know that for 20 data points I need 5 classes, because 2^4= 16 and 2^5= 32
My class width should then be (43-3)/5= 8 right? But if I do that I can't fit all observations in the classes
My classes then look as follows:
Class | Class width
1. | 3-10
2. | 11-18
3. | 19-26
4. | 27-34
5. | 35-42
But then my largest number (43) doesn't fit in it
And if I choose a higher starting point for the classes, then my lowest number of 3 doesn't fit in it
What am I doing wrong?
i use this formula when computing for the number of classes K = 1 + 3.322 log (n) where n is the number of data points. after that, to compute for class width i simply use this C = R / K where R is the range (highest data - lowest data). make sure to round to the nearest integer ex. 5.31 rounds up to 6
THANK YOU SO MUCH THANK YOU, LIKE SERIOUSLY
You could just take the log of both sides instead. So n=2k, in this case, 20=2k, log20=log2k, divide by log2 on both sides and you end up with 4.3 roughly. So 4 classes. Then max value-min value and then divide by classes (4) which equals 8. You would end up with 0-7, 8-15, 16-23, 24-32
Thank you sir
Thank you!!!
thanks a lot, this 2k formula really help! 😃
damn very helpful and very understandable
i have a solution to an assignment where the tutor used 9 as the number of classes for a dataset of 30 data points. Can you comment on it please?
Makes the formula, very efficient and true.
Plz help. Find the number of classes of x? If x=8,10,11,12,13
how do you know what no. of classes to use
why did he make it an inclusive data and not exclusive ?
Plz someone help me how we would know about the frequency??
I also aware of this equation, but I need literature support. would you please provide literature support?
I dont get why you start zero while there is 1 visitor isnt it be in the list ?
Thanks. :)
Amazing.
Thanks you so much that was helpful .. a good clear explanation.
shouldn't the class size be 7?
Thanks Perfect demonstration!
Superb
Thanks for this video lesson.May I use this one for my class?Thanks in advance.
God bless
why can't we use 3^k rule instead of 2^k rule ? can anyone answer please.?
Alomgir Kabir because it's a rule.
really helpful, thanks
Can we use this for exclusive method..please tell me I will subscribe your channel then..
This formula you give (2^k) does NOT work for all cases! I tried - does not work. I can lay it out for you.
Thank you, I'm stupid.
nice and easy thank you !
really? Rounding up 6.4 to whole number 7? how come? it should be 6
try to listen very carefully before you make a comment. 3:05-3:28
round it up. not round off.
idiot
Y 20
the lowest number of observation is 1 not 0..
2 raise to the power of 5 is 32 not 25.
you got 0.1.2.3.4.5.6.... 7 is the size hahahahaha!

Why does it always have to be a video???? No one knows how to explain things without videos anymore?
Hajur in 888
False
my brain fucking hurts now
Thanks
Thank you!
Thanks!
