An excellent video very easy to understand and follow. Thank you.

[@balajitj]

Thank you. I have read the manual but didn't know this model had correlation coefficient feature. This video is very helpful.

[@tonydebling]

This is a very clear no nonsense explanation; I will recommend to my students. Thank you.

[@irembro--1780]

I am thankful for that video!!! I couldnt use my new casio calculator on my hydrolic lessons to find regression and that video was the only source for it

[@bigfootandthesinginggopher3396]

Thank you bigfoot was having a little trouble using and finding the line of best fit with a calculator. But now I can rest easy

Thank you very much, this video was extremely helpful.

Bro great work

So so good

[@thaminduKavinda]

simple and effective

[@MrJason005]

Thanks, the textbook doesn't explain how to do this at all.

[@athena4751]

Bruh if textbook teach you this, who will learn the manual way of doing this. Everybody will start using calculator instead of understanding the basic lol

[@MrJason005]

@@athena4751 What I meant at the time was that the textbook only taught you the mathematical equation method, without showing you how to use the calculator. I didn't wish for that to be wholly replaced, all I meant was that there should be supplementary info on how to do the same thing on the calculator.
In a huge time-pressured environment in an exam, you need to do this type of question rapidly

[@athena4751]

Ah youtube, came in clutch again

what app are you using to record your desktop screen?

[@TheCalculatorGuide]

I use ScreenFlow on a Mac

[@benblackburn1089]

What if we’re missing data?

[@TheCalculatorGuide]

Well, you can only enter the data that is available to you. If you are talking about a question that involves an algebraic aspect then that wouldn't be possible

[@MrBadGuyX]

What's the music called?

[@TheCalculatorGuide]

It's one of my own tracks. It isn't available to download or stream just yet. Maybe soon.

[@MrBadGuyX]

@@TheCalculatorGuide thanks. It's a brilliant piece so I was wondering if you had a download link.
