PPT-Dimensional Analysis (Factor-Label Method)

How can we convert units Measurements Every measurement needs to have a value number and a unit label Without units we have no way of knowing what the actual measurement is Sometimes the units that something is measured in need to be converted into a comparable unit for a calculation. Organized method of problem-solving . Used in chemistry, physics, engineering, and medicine. Communicates the path to scientists that follow your work. Records your own path for your future use. Dimensional Analysis. Dimensional Analysis . Objectives. To increase knowledge of Dimensional Analysis (DA) for calculating medication dosages. Demonstrate the application and usage of Dimensional Analysis (DA) during medication dosage calculation and medication administration. The SMART way. FACTOR-LABEL. (aka DIMENSIONAL ANALYSIS). We convert all the time.. When the values are familiar, it is easy.. When the problem is short it is simple.. But in . chem. , you will need to solve problems that are neither familiar nor short!. Dimensional Analysis. In Chemistry and every-day life you will often need to express a measurement using a different unit than the one that was initially used. . To convert between units we can use . Analysis . (aka . Factor-Label). . This technique involves the use of conversion factors and writing all measurements with both numerical values and the unit of measurement. A conversion factor is where you have the same amount (entity) represented by two different units of measurement with their corresponding numerical values. Lua Augustin, Savannah Guo, and Blair Marquardt. Learning Outcomes. To understand. :. What . is factor analysis.. What is its model.. Latent vs. observable variables; examples of each. .. Potential applications of factor analysis. The purpose of factor analysis is to discover patterns in the relationships among the . variables. Factor Analysis. Form of multiple correlations. Checking for construct validity. Do questions measure the same dimension?. Conversions. Using t. he . Factor Label Method. Scientific Notation. Easier way to write very large and very small numbers. 983,000,000 = 9.83 x 10 . 8. 0.00000983 = 9.83 x 10 . -6. Takes advantage of the fact that:. The basic objective of Factor Analysis is data reduction or structure detection.. The purpose of . data reduction.  is to remove redundant (highly correlated) variables from the data file, perhaps replacing the entire data file with a smaller number of uncorrelated variables..

A way of converting between units for problem solving. Remember all units have to be in meters, kilograms, and seconds. You can also use dimensional analysis as a way of checking your units to make sure your problem is correct. Binod Kumar Bharti. Assistant Professor cum Jr. Scientist. Department of Dairy Chemistry.
