Have an exam tomorrow and you have literally just saved my life!!!! 👏👏👏
Thanks a lot man, really helpful
You're welcome Abhay! I have a few more stats videos in this series you might like to check out ;-)
amazing, you saved me. I had my settings from list 1 and list 2 wrong before pressing var-1.
You sir saved my exam tomorrow
Thank you so much! You've just made IB Biology so much easier!
You have saved my life, I've been doing all of my stats homework by hand all because I couldn't figure out one little setting.
VERY good video! Thank you!!
Hey thanks for the positive feedback!
Thanks! Been looking for a clear example of how to do this.
you deserve more than a like! you save my exam 😊
Good looking out. Really needed to know how to do this.
You're very quiet, but this is awesome, now I can double check my work, and I can do stuff faster than the people in my class who are using a TI-84. The GUI on these calculators seems to be faster and more organized.
I need a fucking ti 84. Cascio are shit
@@robertisham5279 LOL i prefer casio
Thank you sir for helping me for my last minute studying
Just in time!
Yay finally a simple explanation!
Thank you very much, Sir!
dude thanks alot, u saved me.
Glad you found it helpful! I have more maths videos for this calculator here: ua-cam.com/video/1_UYmPA1xHI/v-deo.html
Thank you Mr. Tompkins!!! :)
Very helpful, thankyou so much.
Dude you saved my life
Thank you very much. This helped me tremendously
Wow! This video has hit 100K views. Maybe I should make some more...
Mr Tompkins EdTech please make more!
Can u make more IB SL videos?? U make math so simple!!
thankyou :)
the problems was so similar to BI exams... good
esto me ayudara mas, gracias
THANK YOU!!!!!! Oh My goodness thank you so much!
THANK YOU
Saved my life
Thank you for the tutorial!
You're welcome! You can find more videos for the casio graphic calcs here: ua-cam.com/video/1_UYmPA1xHI/v-deo.html
Thanks man you saved my assss
Thank you, kind Sir.
Thank you SO much!!
Thanks for this treasure!
My pleasure, Esiel hussein!
Congrats on 100k views :)
Thanks Enkaay!
To celebrate 100k views, I have re-recorded the audio and uploaded here: ua-cam.com/video/uzOKleUhc6w/v-deo.html
thank you very much
THANKU
Great work
Thanks a lot!
You're welcome Jeroen! There is also a follow up video here looking at continuous data: : ua-cam.com/video/Z39YQe4K0Yc/v-deo.html
👍keep it up. Thanks
Welcome 👍 - you'll find more of these videos here: ua-cam.com/play/PLxp90x5c0ttY9NNGtmYKFNKPbHV3FNpae.html
THANKS!!
Thank you!
Thanks!
Thnx 4 the video
Is there a way to calculate this with continuous data?
I have made a new video specifically looking at continuous data: ua-cam.com/video/Z39YQe4K0Yc/v-deo.html
Thanks!!!!
You’re welcome Alicia!
thanks a lot! :D just one suggestion...speak a bit louder coz its hard to hear you :)
what should the calculator's settings be in order to complete this process w/o errors?
Thanks I cant fiind my Casio operating manual this helped a lot.
cheers

You chose the wrong SD -you chose the one for the population and not the sample. If you did it manually you will see that the other one -the bigger one. Although I find it weird as dividing by n should give you a smaller number compared with n-1. I think its to do with subtracting a bigger mean and the using the square root of that.
When I made this video, the S1 A level paper did not require students to choose between population and sample formulae for standard deviation, and their formula booklet only gave the one for population. So it was the correct choice for this paper! That said, we are using all the available data here, and not sampling from a larger data set, or making any inferences on shopping baskets generally, and so the population SD would appear to be the most appropriate in any case.
I need to buy a calculator. Are you using it plugged into your computer? Can you use it on a Mac.
I'm using an emulator here, but there are links in the video description to the "real" calculator.
how do you do standard error of mean?
same fam
Hi! That's great video and I have a relates question: Do you now if there is any way of working with continuous variables such as the age of a large sample that has been given in intervals? Thank you in advanced :D
Thanks Rafa! I'm thinking about making a series of these videos and will consider this as a possible future topic.
Mr Tompkins Ed Tech Great!!! Keep up the great job!!! Thanks again :3
Hey Rafa! I have made a new video looking specifically at continuous data here: ua-cam.com/video/Z39YQe4K0Yc/v-deo.html I hope it addresses your question.
What is sx if it is not a standard deviation ? if someone can tell please
It’s also standard deviation, but has a slightly different formula. Sigma x is the standard deviation of a population (a complete large data set) and Sx is the standard deviation of a sample. The first uses n as the divisor and the second uses n-1, and therefore ends up being slightly larger. It’s analogous to using (n+1)/2 for finding a median whereas for large data sets, you just use n/2. Strictly speaking you are meant to pick the right type of standard deviation to match the data you are working with, but for A Level they ignore this and students are normally just taught to use the first one. Mark schemes tend to give full credit for either so don’t stress about it too much!
@@MrTompkins thank you
Would the variance be 1.9044?
how do you do variance?
Variance is simply the square of the standard deviation. So proceed as above and square your final answer
Máy này đc mang vào phòng thi đh ko vậy
It is allowed in UK. I dont know the rules in Vietnam, sorry. Nó được phép ở Anh. Tôi không biết luật lệ ở Việt Nam, xin lỗi.
IB..
I always thought I was intelligent I happened upon one of these calculators today. It was dumped in our car park at work along with other various items. I have zero idea how to use this thing. It is like finding alien technology. I am going to sell it. I am sure some maths genius will appreciate it.
Hey Matt - I'm sure a student studying A Level maths will want it - they sell for £60-£100 new depending on the model, so you should easily get 30-50 for this alien tech - Good find!
@@MrTompkins It's the casio fx-9860gii sd calculator. I listed it on Facebook market for £50 open to offers. I don't particularly want £50 for it. But I thought, start higher and see what I get offered.
Please speak up!
flhines18 the background noise makes it even worse
I have rerecorded the sound and uploaded here: ua-cam.com/video/940w_cNwgK0/v-deo.html
видос 10 из 10, но я так и не понял как с него звонить
спасибо!
Thank you for uploading you really helped, but I feel like I'm watching ASMR, not a casio tutorial...
You sound a bit like Joe Lycett!
I wish I was as drole...:-)
if i would know HOW to make those tabels, that would be great! i dont know how to use this thing and it isnt explained either! ;-; some1 help please
This probably would have been helpful if I could hear ANYTHING you are saying.
Thanks for the feedback. I've now bought a new mic so hopefully future videos will be crystal clear! I've also added captions to all the videos, so if you are still struggling, try turning CC on.
watch on 1.25x speed
Yes, this was made in simpler times, when people were not in such a hurry XD
@@MrTompkins yeah lol I literally have a test in a few hours and I need to master this topic. But thank you so much sir, you cleared all my confusions
Thank you for your tutorial!
You're welcome Ell Aee!
