uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count is 0.1 g. On the small graduated cylinders‚ the least count is 25 ml. If you are using the full precision of the instrument‚ you are probably

and Spectrophotometer Introduction In scientific experiments‚ correct measurements are required to achieve precise and accurate data. Precision is the degree to which several measurements provide answers very close to each other. Accuracy describes the nearness of a measurement to the standard or true value. Certain measuring devices are used to attain precision and accuracy. One example is the Air displacement pipette or the micropipettes. The micropipettes are measuring tools used to transfer

Accuracy and Precision relate to quality of measurement. Accuracy refers to how close the measurements are to the “true” value or accepted standard value or known value. Precision is how close measurements are to each other. Precision is a unit of measurement that is also referred to as the ability to reproduce the same results multiple times. Society is reliant on standard measurements when they buy goods and services. Society depends upon the accuracy and precision of measurements for
