ing the order in which the specimens are to be sampled for the simplest case of sorting into two groups: one group "above" the rating B, and the other group according to the rating H. All the specimens are sorted into those two groups to begin with. In the next series of measurements...
Steps for How to Determine the Minimum & Maximum Possible Area of a Given Shape with Measured Dimensions Step 1:The rule of thumb for the error of a measurement is1/2of the least count of the measuring device used, where the least count is the smallest value ...
How to Determine the Margin of Error for a Given Sample Size Step 1:Identify the sample proportion, {eq}p {/eq}, the sample size {eq}n {/eq}, and the {eq}Z {/eq}-score for the confidence level. Step 2:Substitute the values found in step 1 into the formula {eq}\text...

Typical system-level design starts with a cascade analysis where the low level performance parameters of the building blocks are used to determine the overall performance of the system constructed using these blocks. There are well established analytical formulas and tools that can be used to calcula...
How to Calculate Growth Rates Growth rates can be calculated in several ways, depending on what the figure is intended to convey. A simple growth measurement simply divides the difference between the ending and starting value by the beginning value, or (EV-BV)/BV. Theeconomic growth of a cou...
In practice, the significance level is stated in advance to determine how small the p-value must be to reject the null hypothesis. Because different researchers use different levels of significance when examining a question, a reader may sometimes have difficulty comparing results from two different...
