error'). Experimental uncertainty arises because of: Limits in the how exact the measuring apparatus is. calculating percentage error chemistry This is the precision of the apparatus. Imperfections in experimental procedures. calculating percentage error between two values Judgements made by the operator. When can my results be said to be precise? If you repeat
Calculating Percentage Error Physics
a measurement several times and obtain values that are close together, your results are said to be precise. If the same person obtains these close values, then the

experimental procedure is repeatable. If a number of different people carry out the same measuring procedure and the values are close the procedure is reproducible. What is a systematic error? A systematic error is one that is repeated in each measurement taken. If this is realised after the experimental work is done, it can be taken into how to calculate percentage error in temperature change account in any calculations. What are random errors? Even the most careful and experienced operator cannot avoid random errors. However, their effect can be reduced by carrying out a measurement many times (if the opportunity exists) and working out an average value. Let's look in more detail at 'built-in' uncertainty of some laboratory equipment... Some measurement uncertainties are given below: EquipmentMeasurement to the nearest: Balance (1 decimal place)0.08 g Balance (2 decimal place)0.008 g Balance (3 decimal place)0.0008 g Measuring Cylinder (25 cm3)0.5 cm3 Graduated Pipette (25 cm3, Grade B)0.04 cm3 Burette (50 cm3, Grade B)0.08 cm3 Volumetric Flask (250 cm3, Grade B)0.2 cm3 Stopwatch (digital)0.01 s Calculating the percentage uncertainty (often called percentage error) ... Now try calculating the following percentage uncertainties... 1.00 g on a 2 decimal place balance 10.00 g on a 2 decimal place balance 1.00 g on a 3 decimal place balance 10 cm3 in a 25 cm3 measuring cylinder 25 cm3 in a 25 cm3 measuring cylinder 25 cm3 in

Absolute uncertainty and recording data When you record measurements you should also record the (absolute) uncertainty associated with the measurement The uncertainty reflects greatest precision, i.e. the smallest unit to which a measurement can be made.
