   What is upper bound & lower bound?

   • Upper bound: a value that is greater than or equal to every element of a set of data. But be careful! 2 is also a lower bound (it is less than any element of that set), in fact any value 3 or less is a lower bound. Likewise any value 22 or above is also an upper bound, such as 50 or 1000.

   What is the difference between a tight upper bound and a lower bound?

   • An upper bound is said to be a tight upper bound, a least upper bound, or a supremum, if no smaller value is an upper bound. Similarly, a lower bound is said to be a tight lower bound, a greatest lower bound, or an infimum, if no greater value is a lower bound.

   Is 2 a lower or upper bound?

   • But be careful! 2 is also a lower bound (it is less than any element of that set), in fact any value 3 or less is a lower bound. Likewise any value 22 or above is also an upper bound, such as 50 or 1000. Example: how tall is a human?

   What is the upper and lower bound of a number?

   • Stating 24 as the upper bound when a number is 20 to the nearest 10 . Remember that there are numbers bigger than 24 that would round down to 20 such as 24.9. The upper and lower bounds (when rounding to a multiple of 10 ) should always end in 5 . For example, Using the place value of 100 when a number is 700 to the nearest 10.

   The lower bound is the smallest value that would round up to the estimated value. The upper bound is the smallest value that would round up to the next estimated value. They can also be called limits of accuracy. The upper and lower bounds can be written using error intervals. For example,

   What are upper and lower bounds? The upper and lower bounds of a rounded number are the biggest and smallest values that the number could have been before it was rounded. We often round numbers to a given degree of accuracy, for example to the nearest 1010 or to 11 decimal place.

   Mar 16, 2023 · You can use bounds to calculate the level of accuracy of a calculation. This can be used to decide how to round your answer. e.g. If the lower bound of an value is 8.33217... and the upper bound is 8.33198... The true value is between 8.33217... and 8.33198... Both bounds round to 8.332 to 4sf.
