Give upper and lower bounds for data rounded to a specified accuracy.
E1.10.2 Find upper and lower bounds of the results of calculations which have
Find upper and lower bounds of the results of calculations which have used data rounded to a specified accuracy. e.g. write down the upper bound of a length measured correct to the nearest metre. Example calculations include: • calculate the upper bound of the perimeter or the area of a rectangle given dimensions measured to the nearest centimetre • find the lower bound of the speed given rounded values of distance and time.
