Reliability and Validity are important aspects of research in the human services field. Without reliability and validity researchers results would be useless. This paper will define the types of reliability and validity and give examples of each. Examples of a data collection method and data collection instruments used in human services and managerial research will be given. This paper will look into why it is important to ensure that these data collection methods and instruments are both reliable

Like internal validity‚ there can also be threats to external validity‚ & this can be an explanation of how researchers may be wrong in making a generalisation. For instance‚ researchers may conclude that the results of their study (which was done in a specific place‚ with certain types of people‚ & at a specific time) could be generalised to another context. For instance it could have been at another place‚ with different people‚ at a later time‚ even if these factors are only slightly different

Reliability‚ Validity and Accuracy - what do they mean? (To be read in conjunction with an article originally published in Curriculum Support‚ Science‚ 2001 Vol. 6 No. 3) Reliability and validity are two terms that continue to cause problems for teachers and students. Students in Stage 4/5 are required to evaluate evidence for reliability and validity. In Stage 6 they are required to discuss and explain how they would improve the validity and reliability of a first-hand investigation. They could

Test Reliability and Validity: Evaluation of the GRADE A+ Standardized Reading Assessment Assessment is the key to instruction and intervention‚ but according to Salvia‚ Ysseldyke and Bolt (2007)‚ “reliability is a major consideration in evaluating an assessment procedure” (p. 119). Reliability refers to the stability of a tests’ results over time and test reliability refers to the consistency of scores students would receive on alternate forms of the same test‚ for example Test form A and Test

Critically discuss the notion of labour as a “fictitious commodity”. Provide examples where necessary. This paper outlines the argument of labour as a “fictious commodity” using Polanyi’s work. This paper first define what commodity is and what fictitious commodity is before going into deep details of this topic. Conclusions have been drawn base on the main core of the topic and critiques of fictitious commodity by Polanyi. First‚ a commodity is a good or service that is actively produced

Reliability and Validity When examining the data they have collected‚ it is essential for researchers to determine to what degree is their data consistent. There are many methods by which researchers can assess the reliability of their instruments. Through different statistical procedures‚ researchers will evaluate the reliability coefficient to ascertain to what extent their data is consistent. The reliability coefficient is generally a numerical value between 0.00 and 1.00‚ where the coefficients

the study. To ensure that this was achieved‚ the survey needed to demonstrate validity and reliability. Validity‚ as described by Heale and Twycross (2015‚ 66)‚ examines whether the specific concept has been accurately measured. In contrast‚ according to Floss (2013‚1)‚ reliability refers to the consistency of the instrument to measure the concept. The instrument needed to feature external validity in order for the data collected to be generalised (Heale and Twycross 2015‚ 66). To ensure the instrument

"A grim specter has crept upon us almost unnoticed‚ and this imagined tragedy may easily become a stark reality we all shall know" (Carson 3). "Given time—time not in years but in millennia—life adjusts‚ and a balance has been reached. For time is the essential ingredient; but in the modern world there is no time" (Carson 6). "The chemicals to which life is asked to make its adjustment are no longer merely the calcium and silica and copper and all the rest of the minerals washed out of the rocks
