What is the difference between determinate and indeterminate errors in analytical measurement ?
Answers
Error is the correction appear between measured value and expected value or can be calculated by subtracting the expected value from measured value or vice versa to know how much error is present.
Determinate error is the error which can be determined at any stage and can be rectified at once whereas indeterminate error is the error which is difficult to determine or indefinite.
Determinate error can appear again and again but can be corrected whereas indeterminate error appears rarely and not get eliminated.
Determinate error is systemic error whereas indeterminate error is random error.
Answer:
Concept:
The word "analytical procedure" refers to a description of what must be done during the course of an analysis, without regard for the measurement's quality. In terms of measurement (quality) assurance, a more accurate definition of "analytical technique" can be offered, in which a specified procedure to be followed is expressly coupled with an established correctness of the data obtained.

Answer:
Determinate error is one that can be identified at any time and corrected immediately, whereas indeterminate error is one that is difficult to identify or indefinite. Determinate errors occur frequently but may be addressed, whereas indeterminate errors occur infrequently and cannot be removed.
Determinate error:
- Determinate error is an error that can be identified at any time and corrected immediately.
- Determinate errors can recur, but they can be corrected.
- Determinate errors are those that can be avoided or whose scope can be identified. These are some of them: Errors in operations and personnel: these are the mistakes that resulted from the analyst's inattention.
- If present, a determinate error has the same amount and sign for all measures of the same quantity. Taking numerous measurements does not aid
- in the detection or elimination of the inaccuracy.
Indeterminate error:
- Indeterminate error, on the other hand, is an error that is difficult to determine or undefined.
- Indeterminate errors occur infrequently and are rarely corrected.
- Random errors over which the analyst has no control are known as indeterminate errors. Errors cannot be avoided, however they can be reduced by calibrating instruments, performing blank and control determinations, adding a standard, using an internal standard, or using amplification methods.
