In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. Validity ensures that an experiment can be… evidence. Reliability and validity are the two most important characteristics of the research. The reliability of dependent variables is an issue whose importance is dramatically underestimated in clinical research. Reliability and validity are two important considerations that must be made with any type of data collection. References. The answer is that they conduct research using the measure to confirm that the scores make sense based on their understanding of the construct being measured. In order to assess reliability, the thing being measured must be measured more than once. Editorial. Importance Of Measurement In Research. They help to ensure that an experiment is credible and can be used in Psychology. Like reliability and validity as used in quantitative research are providing springboard to examine what these two terms mean in the qualitative research paradigm, triangulation as used in quantitative research to test the reliability and validity can also illuminate some ways to test or maximize the validity and reliability of a qualitative study. For example, if you wanted to measure the length of a sofa to make sure it would fit through a door, you might measure it twice. Doctoral research requires collecting data. London. Kumar, R. (2000.a) Research Methodology. Methods to Assess Reliability . Internal consistency reliability is more complicated, because in this measure of reliability we are establishing how well each item in a scale measures the same construct. Reliability refers to the ability to consistently produce a given result. When reading research or continued on page 372 Every time research is used, reliability and validity are some of the criteria upon which neuroscience nurses should base their evaluation of research. To do so, it is important to become good consumers of research. If you get an identical measurement twice, you can be confident you measured reliably. Every time research is used, reliability and validity are some of the criteria upon which neuroscience nurses should base their evaluation of research. This is an extremely important point. Reliability and validity are important factors of psychological research studies. Define reliability, including the different types and how they are assessed. In research, reliability and validity are often computed with statistical programs. Every research whether it is in social science or physical science, literature or art there should be reliability and validity in the research. Reliability is important to make sure something can be replicated and that the findings will be the same if the experiment was done again. Education Research and Perspectives, Vol.38, No.1 105 Validity and Reliability in Social Science Research Ellen A. Drost California State University, Los Angeles Concepts of reliability and validity in social science research are introduced and major methods to assess reliability and validity reviewed with examples from the literature. Sage Pub. research effort.” (Trochim, 2006) • “the assigning of numbers to observations in order to quantify phenomena.” (Kimberlin and Winterstein, 2008) • “characterizing individuals in terms of the issues under study.” (Babbie, Halley, Wagner, & Zaino, 2013) As a society, we thirst for measurement. Analyzed data allows doctoral scholars to assess, evaluate, or measure the variables included in the study. Although clinical researchers know that it is important to have valid measures, there is insufficient understanding of the role that reliability plays in correlative validity-the extent to which variables are capable of correlating with each other.
