Definition of Verification
In general the definition of verification written according to wikipedia is a positive logical philosophical theory in choosing the method of experience.
In that sense, that a source 먹튀검증 based on knowledge and savings through logical analysis with the help of logic symbols using methods in solving problems through empirical methods.
This means that if there is something that cannot be verified empirically then this proves a futile result.
The theory, for its adherents has a consequence problem for traditional philosophy, if it is true, it will cause a lot of futile work on the philosophical past, including on metaphysics and ethics.
Validation or validity is measuring the extent of differences in scores that reflect actual differences between individuals, groups, or situations that are about the characteristics to be measured, or also actual errors in individuals or groups of one (1) situation to a situation that is other.
So that the definition of validity in general is a measure that shows the level of validity or validity in an instrument. This means that an instrument will be said or considered valid if able or able to measure what is desired.
As explained the definition of verification above that Verification is often encountered in registration. When registering, it will be necessary to provide objective evidence such as photocopies of ID cards, birth certificates, and the like.
After these things are completed, then the registration file is verified. Apart from that, verification can also be done on the laboratory that will conduct a study.
This Verification Method, is done by using standard properties to prove the correct results. The verification can also be aimed at seeing whether the laboratory has personnel competence.
There are three (3) types of validity that are commonly used in the preparation of instruments, such as content validity, construct validity, understanding and validity of predictions.
Examples of Validation
This validity concerns the accuracy of the measuring instrument against a measured concept, thus measuring exactly what it should be measured.
1. Example of Validation in Measuring Students’ Capabilities in Mathematics
In measuring students’ abilities in mathematics. Then by being given a sentence question Long is so convoluted.
It is intended to give difficulty in capturing the meaning. The end result, the student can not answer, as a result does not understand the question.
2. Examples of Validation in Measuring Learning Achievements
Examples of variable learning achievement and motivation can be measured by tests or questionnaires. This method can also be different, the test can be carried out either in writing or verbally.
Differences in Verification and Validation
This verification and validation aims to show that the system is in accordance with its specifications and that the system meets customer expectations.
Although both verification and validation are related to the examination of a case or problem, whether it is data. However, verification and validation have a profound difference.
- Verification actually speaks to confirmation with a scientific and objective testing process regarding these requirements.
- In contrast to verification, the validation check usually has non-standard nature or by using a separate method carried out in the laboratory.
- Apart from that the validation can also develop its own method in the laboratory. The purpose of this validation is to be able to obtain valid results or not.
So many explanations about Verification & Validation: Understanding, Objectives, Differences and Examples, hopefully can be useful for you.
