Description Reliability (cons******ency) and validity (accuracy) are essential properties of instruments (assessments, inventories, measurement tools) used for measuring variables. There is also internal validity (causal, relational accuracy), and external validity (generalizability of findings) in experimental studies. Using the Freeman-Lozier Library, locate an academic, peer-reviewed journal article that presents either an experimental (Chapter 10) or correlational … Continue reading “essential properties of instruments | My Assignment Tutor”
Description Reliability (cons******ency) and validity (accuracy) are essential properties of instruments (assessments, inventories, measurement tools) used for measuring variables. There is also internal validity (causal, relational accuracy), and external validity (generalizability of findings) in experimental studies. Using the Freeman-Lozier Library, locate an academic, peer-reviewed journal article that presents either an experimental (Chapter 10) or correlational (Chapter 11) study on a topic related to counseling or human services. Provide the APA reference for the article you select (APA publication manual, Chapter 9). Identify the independent and dependent variables in the primary hypothesis of the study (there may be many hypotheses in a single study – pick just one on which to focus, Chapter 10). How were the dependent variable/s measured? (Chapter 5) What evidence is there that the measures used were both valid and reliable? (pp. 157-169) What potential concerns might you have with the way the variables were measured? (Chapters 5 and 10) Were there any thr******s to either internal or external validity of the study? (Chapter 10) What are the key character******ics of experiments to prevent validity thr******s? (Chapter 10)
