Validity And Reliability In Research Methodology

A specific measure is considered to be reliable if its application on the same object of measurement number of times produces the same results.

Validity and reliability in research methodology. Over time test retest reliability across items internal consistency and across different researchers inter rater reliability. Issues of research reliability and validity need to be addressed in methodology chapter in a concise manner. Reliability psychologists consider three types of consistency. There are various methods to measure validity and reliability.

Research reliability can be divided into three categories. Reliability can be measured through various statistical methods depending on the types of validity as explained below. In simple terms research reliability is the degree to which research method produces stable and consistent results. How to assess reliability and validity.

Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method technique or test measures something. In simple terms if your research is associated with high levels of reliability then other researchers need to be able to generate the same results using the same. Reliability can be measured by comparing the consistency of the procedure and its results.
