In this, the results are not considered reliable, giving inconsistent results, and they are not considered to be valid, meaning that something is not accurately measuring something else. refers to measuring reliability by assessing the consistency of observations across raters/judges? place to another, In qualitative research, researchers look for dependability that the results will be subject to change and instability rather than looking for reliability. Lincoln and Guba (1985) used trustworthiness of a study as the naturalists equivalent for internal validation, external validation, reliability, and objectivity. 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.

So in measurement reliability is the consistency with which a test yields the same result in measuring whatever it does measure. Oliver (2010) considers validity to be a compulsory requirement for all types of studies. You can help your audience understand the perspective or social position from which the research was conducted by telling them how you integrated into and interacted with the community you are studying.

If you develop your own questionnaire, it should be based on established theory or the findings of previous studies, and the questions should be carefully and precisely worded. This is why the method is named alternate-forms. It expresses the idea that scientific claims, methods, resultsand scientists themselvesare not, or should not be, influenced by particular perspectives, value judgments, community bias or personal interests, to name a few relevant factors. Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research. However, it was showing consistent results, but it cannot be considered as reliable. 2. True or False: Construct Validityanalyzes the extent to which a test measures theconstructit claims to measure. Reliability and validity are concepts used to evaluate the quality of research. Students who got failed in the pre-final exam are likely to get passed in the final exams; they might be more confident and conscious than earlier. What is the importance of Validity and Reliability in terms of research? Fill in the blank: In_____errors,issues of reliability stem from the actual subjects of the experiments. High reliability is one indicator that a measurement is valid. What is an example of reliability and validity?

Repeatability or test-retest reliability is defined as 'closeness of the agreement between the results of successive measurements of the same measure and carried out under the same conditions' ( Taylor and Kuyatt, 1994, 14), which is guaranteed for any deterministic DL model. Reliability can be measured throughvarious statistical methodsdepending on the types of validity, as explained below: As we discussed above, the reliability of the measurement alone cannot determine its validity. Reliability refers to a study's replicability, while validity refers to a study's accuracy. There are examples of validity in day-to-day life. In contrast, if a method is not reliable, its not valid. Changes in the instruments collaboration. What data do you collect in participant observation? They should be thoroughly researched and based on existing knowledge. Be forthright about you see.

The two types of errors in reliability are random errors and nonrandom errors. Following is a brief summary of some of these issues, with an emphasis on how they might affect students and early career researchers.
