Factors to consider in determining sample size?
Factors that determine sample size
What is the relationship between sample and population?
From a sample of a population, the properties of the population can be inferred.
Factors that determine sample size?
1. population to deal with in the sample 2. Location. ocation where the sample will be done 3. design. how the sample will be taken 4. result. how the outcome will be determined
What is the chief aim of probability sampling is to be able to select?
The chief aim is to find a representative sample; that is, a sample which reflects the properties of the population, as a whole.
When can statistics be used to gain information about a population from a sample?
When the sample - whether it is random or systematic - is somehow representative of the population.
What properties could be used to help determine whether the sample is rreally zinc?
Melting point of the sample & Density of the sample
How can you determine whether a sample is representative of a population?
Take a simple random sample.
How can you determine if something is pure metal?
you will have to determine the properties of your sample, and compare these with a table of properties of metals. Density is a good easy one to start with. But you could consider colour, softness and so on.
How could one determine whether a sample of aspirin is pure or not?
The determination is by chemical analysis.
What is a characteristics of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
What is characteristic property of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
Why can't you use density or reactivity to determine whether a sample of cobalt or nickel?
If you had a piece of metal, you could use these properties to determine which element it is. Iron has different physical and chemical properties than the other two elements. The density of iron is much less than cobalt or nickel, and it reacts with oxygen in the air.
Does hydrochloric acid affect diamond?
No. There are other ways of analyzing a sample to determine whether or not it is diamond, which does not dissolve in hydrochloric acid.
Reasoning which extrapolates from the properties of a sample to the properties of the majority?
Inductive Reasoning
How would one determine whether a given sample of aspirin is pure or not?
if the melting point range is between 0.5 to 1 degree celcius
How do you find whether given sample is DNA or RNA?
A spectrophotometer can be used to know if a sample is DNA or RNA. DNA has an absorbance maximaat 260nm, whereas RNA has an absorbance maxima at 280nm. By looking at which one of these two wavelengths the sample is more excited, one can determine if the sample is DNA or RNA.
How can a forensics lab determine from antibody class alone whether a sample is blood plasma or another body secretion such as semen or tears?
