sample size calculationtwo sample comparisontype I errortype II errorOne of the most important statistical analyses when designing animal and human studies is the calculation of the required sample size. In this review, we define central terms in the context of sample size determination, including ...
Find the population mean, μ (the Greek letter mu). You can calculate this value by adding all of the values in the observed population and then dividing by number of units in this summation, n. This value is often given by default. Step 3 Calculate the sample standard deviation, s. Do...
the Doyle, Scribner and the International 1/4" scales. These scales let you calculate the board feet of groups of logs when you know their diameter at breast height. They consist of a mix of "rule of thumb" measurements and precise calculations that are used for the...
Furthermore, your cat’s vet can teach you how to read pet food/treat nutrition labels and calculate nutrition requirements correctly. This information can be used to calculate how many calories your cat is actually eating. Other nutritional calculations such as resting energy requirements (RER) an...
It is possible to calculate the expected average fragment size for a given genomic DNA if the percent GC content of the DNA and the recognition sequence of the restriction enzyme are known. For example, in a genome with 50% GC content and no dinucleotide bias, a four-cutter can be expecte...
Well, one reason they come in pairs is so animals can calculate distance. But like most features, sight is an adaptation to an ecological niche, leading to a trade-off. Fallow deer doe in Ashdown Forest, Sussex, England. © James Warwick/Getty ...
A statistical procedure to calculate the minimum sample size required to detect an effect of a given size. Pvalue Used in hypothesis testing to help decide whether to reject the null hypothesis; the smaller thePvalue, the more likely it is to reject the null hypothesis. ...
At CALCULATE ROOF HEIGHT from SLOPE & RUN or BUILDING WIDTH you'll see the calculations you can try. Watch out: if you're planning to collect rainwater running off of this roof and then to use it for human or animal consumption in any form, you might first want to check the chemist...
[52] to calculate benthic ODBAs for a grid of the marine area around New I. (approximately 100 km around the island;n= 26,196) separate for each colony and season. For the pelagic ODBAs, we used the corresponding regressions (see Additional file1: Table S2) and the median dive depth...
You can use the information in the last two sections along with one simple formula to calculate the heat absorption in a specific situation. All you need to know is the substance being heated, the change in temperature and the mass of the substance. The equation is: ...
