Derived mean count rate
WebIn transitive terms the difference between count and rate is that count is to consider something an example of something while rate is to berate, scold. In obsolete terms the difference between count and rate is that count is an object of interest or account; value; estimation while rate is ratification; approval. WebThis is easily noticed if one looks at the derived count rate (a parameter that can be calculated and displayed in the software), which would be the theoretical countrate …

WebMeasuring the particle concentration of a sample is similar to measuring its size, but the sample preparation and the effect of sample measurement properties have a greater impact on the concentration measurement than for a standard Dynamic Light … WebHowever, users should note that this method for calculating the MOE and SE for aggregated count data is an approximation, and caution is warranted because this method does not consider the correlation or covariance between the component estimates. This method may result in an overestimate or underestimate of the derived
WebThe count rates of cps and cpm are generally accepted and convenient practical rate measurements. They are not SI units, but are de facto radiological units of measure in widespread use.
