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. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos. Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT.
