Before any scientific article, journal, or experiment can be posted, the findings must first meet standards of both reliability and validity. How do we figure it out? All the planning about reliability and validity will be discussed here, including the chosen samples and size and the techniques used to measure reliability and validity. - Time it takes to move Within the domain of psychological research methods, any errors in the reliability and validity of a test or experiment are very detrimental to the value of the research. Please talk about the level of reliability and validity of your results and their influence on values. Especially, in the thesis and the dissertation, these concepts are adopted much. Reliability and validity are two concepts that are important for defining and measuring bias and distortion.
