standard deviation
Standard deviation the square root of the variance; we generally prefer thinking about error in terms of standard deviation because it yields a number that makes sense using the original scale of measurement.
Measurement Error
Measurement error is the difference between a value we measure and the true value we are trying to measure. Measurement error happens because measurements are rarely perfectly exact. Examples of Measurement Error A scale gives slightly different ...
Sampling Error
Sampling error is the difference between a result calculated from a sample and the corresponding value in the population or data generating process (DGP). Sampling error occurs because different random samples contain different observations. Even ...
SS Error
SS error is the amount of error left unexplained by the model; the area of all the squared residuals based on the distance of each score from the model prediction.
margin of error
Margin of error is also called critical distance; the distance between the boundaries of the "unlikely" area for a sampling distribution and the mean of that distribution expressed in the same unit as the variable (e.g., mm, lbs, dollars).
