What are the sources of determinate errors?

The basis of determinate or systematic errors arises from three sources: ● the analyst or operator; ● the equipment (apparatus and instrumentation) and the laboratory environment; ● the method or procedure.

What is determinate error?

Determinate errors are the errors which can be avoided or the extent of error can be determined. These include: Operational and personal errors: These are the errors occurred because of the analyst’s inattention. They can be avoided with proper care and experience of the analyst.

What is error What are determinate and indeterminate errors What are the sources of determinate and indeterminate errors How can they be minimized?

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.

What is an error in chemistry?

error: The difference between the experimental and accepted values. experimental value: The value that is measured during the experiment.

What are the types of random error?

There are two types of random error: observational and environmental.

• Random observational errors are not predictable. They fluctuate between being too high or too low.
• Environmental errors are caused by the laboratory environment. An example might be a malfunctioning instrument.

How does parallax error occur?

Parallax error occurs when the measurement of an object’s length is more or less than the true length because of your eye being positioned at an angle to the measurement markings. A wider edge allows for a larger parallax error because the object could be higher or lower with respect to the true measurement marking.

What are determinate and indeterminate structures?

1. When all forces in a structure is determined from equilibrium equations, the structure is known as statically determinate. When the unknown forces in a structure are more than the available equilibrium equations, that structure is known as statically indeterminate structure.

What are errors and classify them?

Errors are classified in two types – Systemic (Determinate) and Random (Indeterminate) errors. Systemic (Determinate) errors: Errors which can be avoided or whose magnitude can be determined is called as systemic errors. It can be determinable and presumably can be either avoided or corrected.
