Exploring Reliability and Validity Lynetric Rivers Liberty University Abstract This paper will focus on the types of reliability and validity used in the Values and Motives Questionnaire. Also this writer will be investigating areas of concerns and strengths as it relates to the Values and Motives Questionnaire, well as formulating an opinion of the test (VMQ) with the material presented. This writer will further conveying information concerning the sample size, nature of population that
of 71 or above). There is sufficient evidence of reliability and validity for the BASC -2 BESS assessment. The screening proves to have a high rate of internal consistency, test-retest reliability, and inter-rater reliability. According to the authors Reynolds & Kamphaus (2007), internal consistency was measured through split –half reliability among teachers, parents and students with coefficients ranging from .90 to.97. Test- retest reliability was measured by subgroups of the total sample for
used differently depending on the organization. This dissertation will analyze two authors perspective on what is theory? What makes up a good theory? What criteria are used by scholars to evaluate theory and research? Also an outlining on reliability and validity, and identify different measurement used in criminal justice. Last a discussion about classical school and positivist will also be presented. A. In the book “Criminological Theories” written by Akers & Sellers, describes theory as “An effective
can be utilized to assess validity and reliability of a survey instrument. These approaches are used to make certain that the survey instrument accurately captures the data that is need as well as provides reliable results of over time (Phillips, Phillips, Aaron, 2013). To assess, the validity and reliability of a survey instrument, researchers conduct a review of validity and reliability during survey pilot testing (Phillips et al., 2013). In exploring reliability, there are four types in survey
tests and assessments validity refers to the degree where theoretical and empirical evidence supports the meaning and interpretation of the test scores (Reynolds & Livingston, 2013). Validity is important in testing and assessment as validity refers to credibility from a trustworthy source. In this respect, validity is important for scientist and professionals to select appropriate methods that support the meaning and interpretation of test scores. In psychology, reliability is concerned with stability
Reliability and Validity Paper University of Phoenix BSHS 352 The profession of human service uses an enormous quantify of information to conduct test in the process of service delivery. The data assembled goes to a panel of assessment when deciding the option that will best fit the interest of the population, or the experiment idea in question. The content of this paper will define, and describe the different types of reliability, and validity. In addition display examples of data collection
While the full version DASS is used in both clinical and research settings, the DASS-21 is typically used for research purposes (Lovibond, 2013). As such this paper will evaluate the empirical evidence for the validity and reliability of the DASS-21 for research purposes. Evidence for Validity The DASS-21 shares many similarities with the tripartite model of depression (Brown, Chorpita, Korotitsch, & Barlow, 1997), which posits that the explanation of an affective domain requires the evaluation of
Developmental Inventory, and the Mullen Scales of Early Learning; are used to assess generalized development (Burns et al., 2013). Validity, reliability, comprehensive, and user friendly are qualities of an assessment tool that produces accurate results. The ASQ -3 has demonstrated these qualities and is utilized in many cultures and countries (McKnight, 2014). When exploring the basic biological functioning and well-being of the pediatric patient; social-emotional and motor skills will be assessed.
precision. However several other studies contradict this finding. Testa et al. (2007) has found that CHOL PET is less sensitive than 3D MRI, while Groenendaal et al. (2010) argues that DW MRI should not be used for tumor delineation due to its poor reliability. More studies such as Kato et al. (2002) and Mena et al. (2012) which investigated uptake choline-11 revealed that Chol PET could not differentiate between benign and malignant prostatic tissues. Kato et al. (2002) also found slight correlation
reports using the mail-in scoring service, costing $75.50. One can find these resources at www.pearsonclinical.com/talent/products/100000323/campbell-interest-and-skill-survey-ciss.html. Since this would be considered a formal assessment, validity and reliability are characteristics that can be identified. I would consider this to be a formal assessment because this assessment measures inventory (no right or wrong answers) and also measures skill. A norm amongst this assessment is working adults.
