Accuracy refers to how close measurements are to the true value, while precision refers to how close measurements are to each other in other words, accuracy describes the difference between the measurement and the part's actual value, while precision describes the variation you see when you measure the same part repeatedly with the same.

Demonstrate- c a lculate the density using a graph know- un derstand the difference between precision and accuracy understand- connect the concept of significant figures to precision of measuring tools. Using the density of water at the temperature recorded (available in the crc handbook of chemistry and physics) or the specific volume of water from the activity use of the analytical balance, calculate the mass of 1000 ml of water. These differences in execution can affect the accuracy, precision and trueness of results being released from the clinical or research lab to ensure pipetting accuracy, facilities should adopt standard operating procedures for pipetting techniques and ensure that all operators are trained to an adequate level of proficiency. The graph of mass vs volume places volume on the x-axis and the mass on the y-axis the value of graphing this relationship is best understood by considering the following equation #d=m/v.
