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 ...
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.
sampling error
Sampling error is the variation that occurs from sample to sample due to the fact that no sample is a perfect representation of the population; can be biased or unbiased; also known as sampling variation.
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).
