What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
As the sample size increases the effect of an extreme value on the sample mean becomes smaller.?
yes
How can you use congress in a sentence?
Congress is the Legislative Branch of government which primarily creates laws. A sample sentence is: "Congress recently passed a bill that was vetoed by the President".
How does sample size effect the test statistic?
The larger the sample size, the more accurate the test results.
What is the effect if the sample size not according to the standart specification by ISRM?

What is a part of a population callded?
Population is a noun.
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.
Does the size of a sample affect the values of the frequency table?
Yes. If the sample is a random drawing from the population, then as the size increases, the relative frequency of each interval from the sample should be a better estimate of the relative frequency in the population. Now, in practical terms, increasing a small sample will have a larger effect than increasing a large sample. For example, increasing a sample from 10 to 100 will have a larger effect than increasing a sample from 1000 to 10,000. The one exception to this, that I can think of, is if the focus of the study is on a very rare occurrence.
How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
A sample of rainwater is tested with a universal indicator so what does this tell you about rainwater?
A liquid dilution system which dilutes a sample to be analyzed with a carrier to supply a diluted sample-containing liquid to an analytical measurement apparatus of flow type. The inventive dilution system features simplicity and versatility as compared to conventional automatic apparatus with robot concept, and the present system comprises: a first carrier pump for feeding a first carrier; a sample injection unit for injecting the sample into the first carrier; a main passage for flowing a liquid from the sample injection unit to a detector unit of an analytical measurement apparatus; a branching device located downstream of the sample injection unit for forming a branched passage to remove a liquid mass partially from the main passage; a confluence unit located downstream of the branching unit for confluencing a second carrier; and a second carrier pump for feeding the second carrier to the confluence unit. Dilution and mixing of the sample with a carrier is done twice, once at the sample injection and then again at confluence.
What condition should use the standard addition method?
The standard addition would be used when determining the concentration of a sample because of matrix effect problems (matrix effect occurs when unknown sample contains many impurities).
How do sampling methods effect the rigor of a study?
A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.
