Sample is subset of the population so sample size and population size is different.
However, as a subset can be the whole set, if the sample size equals the population size, you have sampled the entire population and you will be 100% accurate with your results; it may cost much more than surveying a [representative] sample, but you get the satisfaction of knowing for what you surveyed the population exactly.
Using a sample is a trade off between the cost of surveying the whole population and accuracy of the result.
A census is a survey of the whole population and could be considered that the sample size = population size; in this case the results are 100% accurate.
The television viewing figures are calculated using a sample of the whole population and then extrapolating them to the whole population; depending upon how the same was chosen, including its size, will affect the accuracy of the results - most likely not more than 95% accurate.
With a carefully selected (that is properly biased) sample you can prove almost anything!
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
Sample size = SQRT(8000) +1 =90
Sample size is the number of samples arawn from a population. If you drew 20 samples, your sample size would be 20.
There is nothing particularly significant about a sample size of 30.

From a sample of a population, the properties of the population can be inferred.
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
Sample size = SQRT(8000) +1 =90

The sample size is the number of elements, out of a population, for which some data are measured in order to make assessments about the population.
N is neither the sample or population mean. The letter N represents the population size while the small case letter n represents sample size. The symbol of sample mean is x̄ ,while the symbol for population mean is µ.
