Verification & Validation: Definition, Difference, Purpose, Examples
Maybe some people don't know what verification and validation are, so that it's easier to find out with an explanation.
Definition of Verification
According to Wikipedia, the notion of verification is a logical positive philosophical theory in choosing experiential methods. It can be interpreted as a source based on knowledge and observation through logical analysis with the help of logical symbols and problem solving through empirical methods.
This means that if there is something that cannot be verified empirically then it proves a futile result. In this method there is a problem of consequences for traditional philosophy, as it will lead to a lot of wasted work on past philosophies such as ethics and metaphysics.
The definition of verification according to KBBI is an examination of or regarding the truth of reports, statements, calculations and so on.
Definition of Validation
Validity or commonly called Validation is the extent to which the difference in scores reflects the actual differences either individually or in groups. It can also be about the characteristics to be measured or the actual errors that are the same from one situation to another.
In general, the notion of validation is a measure that shows the level of validity or truth of an instrument, which will be said to be valid or not if it can or is able to measure what is being measured want.
The Difference between Validation and Verification
This Validation and Verification has the aim of showing that the system is in accordance with the specifications and that the system meets customer expectations;
In contrast to verification, the validation check usually has a non-standard nature or uses a separate method which is carried out in a laboratory; Apart from that this validation can also develop its own method in the laboratory. The purpose of this validation is to be able to obtain valid or not valid results;
Although both Validation and Verification are related in examining a case or both problems are data, but Validation and Verification have different differences deep;

Verification Example
We often encounter verification at various moments, especially when completing certain requirements. For example in registration which requires several documents as objective evidence such as photocopies of birth certificates, diplomas, ID cards or others. When it is complete, the next step is to verify it, and it can also be carried out in a laboratory that will conduct a study.
In this case it is done by using standard properties to get proof of results that are truly valid. This aims to be able to see whether the laboratory has personnel competence.
Example Validation
There are 3 types of validation that are commonly used in the preparation of instruments, including understanding construct validation, predictive validation and content validation. This relates to the accuracy of measuring instruments on a concept to be measured which requires measuring what should be measured.
Measuring Students' Abilities in Mathematics
