A parameter is a characteristic of a population. A statistic is a characteristic of a sample. Inferential statistics enables you to make an educated guess about a population parameter based on a statistic computed from a sample randomly drawn from that population (see Figure 1). Figure 1.Illustration of the relationship between samples and 1.3 Basic Multivariate Parameters & Statistics First let us clarify the difference between the population and sample. In thinking about statistical inference it is useful to distinguish between samples and populations.

Figure 1.Illustration of the relationship between samples and Difference Between Parametric and Nonparametric Tests 1) Making assumptions. As I’ve mentioned, the parametric test makes assumptions about the population. It needs the parameters that are connected to the normal distribution that is used in the analysis, and the only way to know these parameters is to have some knowledge about the population
In reality, one generally doesn't know the true mean values of the characteristics of the population, which is of course why we are trying to estimate them from samples.

What is the difference between Parameter and Statistic? • Parameter is a descriptive measure of the population, and statistics is a descriptive measure of a sample. • Parameters are not directly calculable, but statistics are calculable and directly observable. A simple idea that helps explain a lot of disagreements is that there’s a difference between a statistic and a fact, and it’s really hard to tell the two apart. A statistic is just a number. And numbers are as easily manipulatable, incomplete, and misleading as words are. But they’re more dangerous than words, because numbers are
