In “regular” mathematics, a parameter refers to a value within an equation that is transferred throughout the equation. For example,mandbare parameters in the slope equationy=mx+b. However, the parameter definition in statistics is quite different. Parameters in statistics are used to describe ...

Researchers and Parameters vs Statistics Researchers are usually more interested in understanding population parameters. After all, understanding the properties of a relatively small sample isn’t valuable by itself. For example, scientists don’t care about a new medicine’s meaneffecton just a few ...

For example, you randomly poll voters in an election. You find that 55% of the population plans to vote for candidate A. That is astatistic. Why? You only asked a sample—a small percentage— of the population who they are voting for. You calculated what the population waslikelyto...
A parameter in statistics refers to an aspect of a population, as opposed to a statistic, which refers to an aspect about a sample. For example, the population mean is a parameter, while the sample mean is a statistic. A parametric statistical test makes an assumption about the population ...

Generally, we use statistics computed from the parameter variance-covariance matrix, rather than elements of the matrix itself. 2. Parameter Variances and Covariances (Book, p. 126) In regression, the parameter values are estimated indirectly using observations. ...
