Reliability and validity are two important parts of any successful research. Different research scholars have come up with insightful ways to shed light on validity vs reliability. When you write a dissertation, the quality assessment of your research depends on two factors. According to the experts, the measurement procedure must be trustable for a study to be considered valid. Reliability defines as the degree to which the research method produces consistent and stable results.
Validity and reliability are both about how good a method measures something:
- Reliability defines to the consistency of a measure (where the results can be reproduced under the same conditions).
- Validity refers to the accuracy of a measure (whether the results really do show what they are supposed to measure).
