The experimental control is a technique for dealing with observational error.

The asteroid was found to be in the expected position to within observational errors.
3.
Margin of error is often used in non-survey contexts to indicate observational error in reporting measured quantities.

In a letter to Bessel dated 2 August 1836 Hagen presented his hypothesis of elementary errors and deduced a Gaussian distribution for observational errors.
6.
Hubble's skepticism about the universe being too small, dense, and young turned out to be based on an observational error.
7.
Instead, two other periodicities were detected at 8.78 and 40.0 days, with amplitudes below the HET observational errors.
8.
The term " observational error " is also sometimes used to refer to response errors and some other types of non-sampling error . and Bland and Altman ( 1996 ).
9.
The fields of probability and statistics frequently use the normal distribution as a simple model for complex phenomena; for example, scientists generally assume that the observational error in most experiments follows a normal distribution.
10.
If no value of the rotation parameter is successful and theory is not within observational error, a modification of physical law is considered, for example, dark matter is invoked to explain the galactic rotation curve.
