There are two types of systematic error which are offset error and scale factor error.
There are four types of systematic error: observational, instrumental, environmental, and theoretical.
Systematic error (also called systematic bias) is consistent, repeatable error associated with faulty equipment or a flawed experiment design.
We can sort survey error into two types – sampling and non-sampling error.Sampling error is a natural effect of using a sample to study a larger population. It's the extent to which the sample differs from the population. ... Non-sampling error is where there's a problem with how the survey is set up and carried out.
Solution : Systematic error is reproducible inaccuracies that are consistently in the same direction. They can be classified as
(i) Instrumental errors,
(ii) Imperfection in experimental technique or procedure
(iii) Personal errors.
(iv) Errors due to external causes
(v) Least count error.
three typesGenerally errors are classified into three types: systematic errors, random errors and blunders. Gross errors are caused by mistake in using instruments or meters, calculating measurement and recording data results.
Systematic errors can also be detected by measuring already known quantities. For example, a spectrometer fitted with a diffraction grating may be checked by using it to measure the wavelength of the D-lines of the sodium electromagnetic spectrum which are at 600 nm and 589.6 nm.
Generally errors are classified into three types: systematic errors, random errors and blunders....In order to understand the concept of systematic errors, let us classify the errors as:Instrumental Errors.Environmental Errors.Observational Errors.Theoritical.
For example, for the A3CSH system, the random error was treated as the averaged uncertainty of the reference acids (±2.2 kcal/mol) divided by the square root of the number of the reference acids, (2.2/√6) = 0.9 kcal/mol, and the systematic error was assigned as √2.2 = 1.5kcal/mol.
In general, sampling errors can be placed into four categories: population-specific error, selection error, sample frame error, or non-response error. A population-specific error occurs when the researcher does not understand who they should survey.
The total error of the survey estimate results from the two types of error:sampling error, which arises when only a part of the population is used to represent the whole population; and.non-sampling error which can occur at any stage of a sample survey and can also occur with censuses.
