Introduction Wrong or inaccurate measurements can lead to wrong decisions‚ which can have serious consequences‚ costing money and even lives. The human and financial consequences of wrong decisions based on poor measurement being taken in matters as important as environmental change and pollution are almost incalculable. It is important therefore to have reliable and accurate measurements which are agreed and accepted by the relevant authorities worldwide. Metrologists are therefore continuously

Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined

performance measurement should broader its measurement scope from external to internal‚ long-term as well as short-term and “soft” as well as “hard” measure (Slack and Lewis‚ 2008). Implicitly‚ a more complex aggregation of performance target model is needed to perform a more detail and organized performance measurement. Significant effort has been established to develop criterion for each performance target which is a core assessment area for Detailed Performance Measures. The measurement for each

According to Hatry performance management will be greatly affected by technology‚ and it will be used increasingly by public administrators with considerable training in both performance measurement and performance management (211). Technology can also help the organization lower its cost which can improve employee performance. Corporations can lower administrative costs‚ third-party consulting costs and typical services costs by better managing

Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The 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

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy
