What are the ethical considerations of fieldwork? Example:Your weighing scale shows different results each time you weigh yourself within a day even after handling it carefully, and weighing before and after meals. How did you plan your research to ensure reliability and validity of the measures used? These two concepts go hand in hand during research and contribute to the credibility of the investigation. Literature Review The evidence of validity and reliability are prerequisites to assure the integrity and quality of a measurement instrument [Kimberlin & Winterstein, 2008]. Reliability refers to how consistently a method measures something. Fleishman's (1972) perceptual motor ability categories. To obtain useful results, the methods you use to collect your data must be valid: the research must be measuring what it claims to measure. Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). They also assure readers that the findings of the study are credible and trustworthy. Validation of the Subjective and Objective Family Burden Interview (SOFBI/ECFOS) in Primary Caregivers to Adults with Intellectual Disabilities Living in the Community refers to measuring reliability by assessing the consistency of observations across raters/judges? Validity is harder to assess than reliability, but it is even more important. Characteristic # 1. True or False:When there is a consistent and repeating correlation found in results, the test or tests will be considered reliable in their results. The relationship between the studys situation and the situations outside the study is considered external validity. This consistency and dependability add value to the tests being used in research.

A test that is considered reliable will show similar outcomes each time it is administered. Validity and Validation is an introduction to validity theory and to the methods used to obtain evidence for the validity of research and assessment results. Reliability is the presence of a stable and constant outcome after repeated measurement or test. how does it change in lifestyles, Journals are publishing more articles that are cross-disciplines, Studies are being seen in journals for professional topics, This means more research than ever before is being conducted and shared though publication, Greater diversity and breadth of knowledge in the field, Post 1980 technology has created new avenues for research questions, faster data analysis, The stakes become even higher when the results inform policy, future scientific studies, or people's health decisions. Issues are still raised even now in the 21st century by the persistent concern with achieving rigor in qualitative research. Reliability: The dictionary meaning of reliability is consistency, dependence or trust. Reliable but not valid. During a long-term experiment, subjects may feel tired, bored, and hungry. 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 research methods under similar conditions. True or False: Alternate-Forms Reliability is when a studysplits the test into twoparts and measures the stability between measurement items in both test halves. Could the passage of time interfere with the initial performance of the test? By sharing how information was gathered, you enable anyone else to repeat your research and draw similar conclusions.
