The mean of any large sample, correctly drawn from a population with finite variance tend towards the population. Aka drawing the mean from random samples of the population will form a normal distribution. As the sample size gets bigger mean more likely to equal population mean. Generalizability refers to the degree to which the results of a study can be applied to a larger population, or the degree to which time- and place-specific findings, taken together, can result in a universal theory.

Variation is a measure of the spread of data around the mean. Standard deviation is the square root of variation and helps approximate what percentage of the population falls between a range of values relative to the mean. As the sample size increases, standard error, which depends on standard deviation and sample size, decreases.
