What is the difference between sample size and sample unit?
sample size is the specific size of a thing like the how long or wide. while sample unit is the whole thing not referring to specific number size.
What determines size difference between sample mean and population mean?
standard error
What is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
What is a sampling ratio?
It is the ratio between the size of the sample and the size of the population.
What is the similarities between population and sample?
Similarity: Both are counts of people/animals/things. Difference: Population is the total # of things, while sample is the # of things that you gather data on. If you pick the right sample size, you can be pretty confident that the results of the sample data is the same as the results of the entire population.

As the sample size increase the difference between the sample mean and the population mean approaches what?
Zero
What determines size difference between sample mean and population mean?
standard error
What is the difference between the population and sample regression functions Is this a distinction without difference?
What is the difference between the population and sample regression functions? Is this a distinction without difference?
What is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
What is a sampling ratio?
It is the ratio between the size of the sample and the size of the population.
What is the relationship between sample and population?
From a sample of a population, the properties of the population can be inferred.
What is the similarities between population and sample?
Similarity: Both are counts of people/animals/things. Difference: Population is the total # of things, while sample is the # of things that you gather data on. If you pick the right sample size, you can be pretty confident that the results of the sample data is the same as the results of the entire population.
How To get valid results small samples are sufficient?
I will assume the sample is random. In general, the larger the sample, the smaller the percentage error will be (the difference between percentages in the sample, and the percentages in the universe from whence the sample is taken). The percentage error tends to go down as the square root of the size of the sample.
What term defined as the size of the association between two variables independent of the sample size?
There is no such term. The regression (or correlation) coefficient changes as the sample size increases - towards its "true" value. There is no measure of association that is independent of sample size.
What are the Difference between Probabilistic sampling methods and non probabilistic sampling methods?
With a probabilistic method, each member of the population has the same probability of being selected for the sample. Equivalently, given a sample size, every sample of that size has the same probability of being the sample which is selected. With such a sample it is easier to find an unbiased estimate of common statistical measures. None of this is true for non-probabilistic sampling.
