Upper & Lower Bounds | Number | Maths | FuseSchool

In this video we discover what bounds. All measurements are approximate. Measurements are given to the nearest practical unit, like a cm or mm or gram. There is then a group of numbers that the original measurement is somewhere between. This is the limits of accuracy. There is a largest possible number called the upper bound. And a lowest possible number called the lower bound. Some people find it very easy to just visualise what the bounds of a measurement are. But there is also a simple method we can use: half the degree of accuracy, and then add or subtract this from the rounded value to get the upper and lower bounds. The degree of accuracy could be a measurement rounded to a nearest unit, or a number round to a certain amount of decimal places or rounded to significant figures. In part 2 we will look at how to calculate with bounds.

[hangbuiminh]

I understand it. OMG i will have a final exam tomorrow. Thank you so

[rehya]

Thanks, I had a question like 2:59 and this video really helped with my homework. Thanks FuseSchool - Global Education, I found this straightforward, useful and fun!
(a quick tip would be you went a little bit slower)

[raphaeathar]

Thank you for explaining this really nicely and now this concept is clear to me

[naomitiyan]

Thank you so much you guys are a life saver i understood very quickly

Thank you so much for this video. I have a few questions, if you don't mind.
1. How can I know what the limits of accuracy is? I mean, how can I half that number if I don't know what that number is or how to get it.
2. I don't get how to figure out the significant digits and the decimal places transformation. I made mistakes in the exercises because of that. For example, I got that the lower bound to 8.762 rounded to 3 decimal places was 8.76195 because I assumed that the exact number would have to have 4 decimal places, which might mean that the limits of accuracy would be 0.0001 which I have to half and gives 0.00005.
3. I searched for lower and upper bound and got to your video because I'm working on linguistic materials where the author referred to these terms. How can we apply these notions to more abstract elements? Maybe you can recommend some handbook or the like meant for dummies or something.
Thank you in advance for the light you can shed on my confusion.

Tysm your video is the only one I understood

[tembusolomon]

She's so pleasant. I keep rewatching the video, not to learn anything but just to watch her speak. And let me say that numbers like 10, 100, 1000 etc do not follow this rule. Cheers!

What a helpful video! Thank you! 😁

[Jay-kztd]

This was a life saver! Thanks so much!

[ayezashakeel]

This video is so helpful I just couldn't understand upper and lower bound but this video does the magic.
Thank you

[venuraweeramanthree]

Thank you sooo much .. I learned new things whoch weren't leant in the school .. help ful and subscribed.. thank you.

[kazishahjalal]

Wow, this is the easiest way. Thank you very much.
