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

Physiological measurements Body Temperature: This is the body ability of the body to generate and get rid of heat. It is measured via the mouth‚ ear‚ forehead and armpit. The hypothalamus in the brain regulates body temperature. Body temperature is maintained by constant burning of fuel in cells. It burns carbohydrates and fat. This constant burning of fuel is a chemical reaction of carbohydrates/fat with oxygen. This will be converted to CO2‚ water and heat and it is due to that heat the body

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food

Performance Measurements To ensure that the organizations goals and objectives are achieved‚ organizations are now using performance measurement tools to achieve them. To improve the process of production‚ to evaluate and control it is a good idea to have performance measurements in place. Performance measurements also can be useful in making decisions and judgments. An organization will also be able used to compare the performance of departments‚ teams and‚ individuals.

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
