What is the difference between grab and composite samples?
A composite sample is taken over a period of time, while a grab sample is a snap shot of what is in your well at the time you take the sample. Homeowner samples are generally grab samples.
Is the distribution of sample means always a normal distribution If not why?
It need not be if: the number of samples is small; the elements within each sample, and the samples themselves are not selected independently.
What is sample trafficking?
Sample trafficking is part of the job duties for public relations. It includes sending items out in a timely manner, checking in return samples, and tracking samples.
How does sample size affect the size of your standard error?
The standard error should decrease as the sample size increases. For larger samples, the standard error is inversely proportional to the square root of the sample size.The standard error should decrease as the sample size increases. For larger samples, the standard error is inversely proportional to the square root of the sample size.The standard error should decrease as the sample size increases.

For larger samples, the standard error is inversely proportional to the square root of the sample size.
Which of the following samples will produce the largest value for the estimated standard error?
A small sample size and a large sample variance.
What uses the ratio of a parent to daughter material found in a sample to find the samples age?
rudametric dating
What uses the ratio of parent to daughter material found in a sample to find a samples age?
rudametric dating
What is the samples of compounds?
A sample is a small portion from a material.
What do you need for radiometric dating?
For radiometric dating, you need a sample of the material you want to date, a method to isolate the parent and daughter isotopes in the sample, and a way to measure the concentrations of these isotopes accurately. Additionally, you need to know the half-life of the parent isotope to calculate the age of the sample.
What is the effect of shape on the density of samples of the same material?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
What is the sample size definition?
Sample size is the number of samples arawn from a population. If you drew 20 samples, your sample size would be 20.
What is age correction for isotopic data?
Age correcting isotopic data is a method to "see through" recent changes in a sample's isotopic ratios. This is done by calculating the amount of decay that has occured since the was emplaced by using the parent/daughter ratio of the sample and its age. This method is commonly used to determine the source of a sample and if that source is common among a set of samples. Put another way: age correction corrects for the dispersion in isotopic ratios that occurs from in-situ decay of variably fractionated parent/daughter ratios during igneous processes.
How is radiometric dating measured?
Radiometric dating is measured by analyzing the decay of radioactive isotopes in rocks and minerals. Scientists measure the ratio of parent isotopes to daughter isotopes to determine the age of a sample. By calculating the rate at which the parent isotope decays into the daughter isotope, the age of the sample can be estimated.
What variable are these samples if There are 8 participants in both samplesbut sample 1 are younger and sample 2 are older?
Variables are variable and samples are samples. Variables are not samples so the question has no meaning.
Which material is used for making paper?
emery paper is used for rough polishing of samples and it give the shinny ,smooth nature for the sample
