    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

    Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

    was laboratory techniques and measurements. The purpose of this lab was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature‚ time
