quantities. All engineers must use the same language in their communications‚ and one of these universal communication tools is the units of measurements. Physical quantities such as length‚ weight‚ time‚ speed‚ force‚ and mass are measured with standard units. Therefore the magnitude if a physical quantity is given by a number and standard unit of measurement. Examples: 5 meters‚ 60 kilograms. SI units are the international system of units (system international). The SI Base Units for the seven

Laboratory Experiment No. 1: Common Laboratory Procedures Objective In this experiment‚ the objectives were to use a balance and measure the volume of the liquids. Theory In the experiment‚ three calculations were used. These are the density‚ relative error and the standard deviation. Density is refers to the mass (m) per unit volume (V) of a material and is often represented by the symbols d or ρ‚ where d = m/V. The density of an object changes with pressure and temperature. Second‚

Nominal Level of Measurement The nominal level of measurement is the lowest of the four ways to characterize data. Nominal means "in name only" and that should help to remember what this level is all about. Nominal data deals with names‚ categories‚ or labels. Data at the nominal level is qualitative. Colors of eyes‚ yes or no responses to a survey‚ and favorite breakfast cereal all deal with the nominal level of measurement. Even some things with numbers associated with them‚ such as a number

Lab Report: MEASUREMENT OF VITAMIN C Introduction Nutritional diseases were once the number one cause of death only a century ago‚ but rarely affect our lives today. The complete lack of vitamin C (ascorbic acid) characterized by dark purple spots on the skin and rotting gums‚ a disease called scurvy‚ took the lives of many sailors up until the mid 1800s when the prevention was discovered. Consequently‚ British sailors became referred to as ‘limeys’ because of their daily habit of eating

Experiment 1: Errors‚ Uncertainties‚ and Measurements Laboratory Report Margarita Andrea S. de Guzman‚ Celine Mae H. Duran‚ Celina Angeline P. Garcia‚ Anna Patricia V. Gerong Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Abstract Measurements‚ defined as a comparison with a standard‚ are essential in the study of physics. However‚ all measurements are prone to errors. There are two sources of errors: systematic errors random errors.
