LMSW Exam: Research and Statistics Questions and Correct Answers the Latest Update

problem formulation the process researchers use to develop a precise statement that can be operationalized. The problem formulation must be stated in a way that ultimately lends itself to measurement. The research problem is connected through a literature search to other related problems and knowledge. research is cumulative concerns about study design - design of test or survey instruments to insure that the data collected is the same for all participants depends on; training of interviewers, and management and control of data - research resources available; resources include subjects, the availability of existing data, and the quality of the professional researchers. funding is an important and often determines the compromises the researchers make - this, in turn, affects the "level of certainty" that can be established - level of certainty needed by consumers of the research - involvement of human subjects - ethics - time available for research main ethical concerns of research #Examify | #OnlineExams | #TestPrep | #StudyResources | #AcademicSuccess | #ExamPreparation | #QuizTime | #LearningTools | #Education | #StudentSupport Examify | Smart Grades | Latest update research cannot lead to harming clients denial of an intervention may constitute harm informed consent confidentiality intervening and extraneous variable mediating variable it modifies or confounds the variation of the dependent variable, which was thought to results from the effects of the independent variable exploratory studies used to explore an area of knowledge where little is known and to gain familiarity with real life settings, problems, or phenomena used to clarify concepts and to develop hypotheses for subsequent research while used to explore new areas, they are built on careful assessment of knowledge that already exists - may include a systematic review of related literature descriptive studies concerned with ascertaining facts and are carefully designed studies of phenomena they attempt to develop an accurate qualitative and/or quantitative summary or systematic and well-defined sample is carefully constructed to avoid bias may be used to describe the characteristics of a population experimental studies #Examify | #OnlineExams | #TestPrep | #StudyResources | #AcademicSuccess | #ExamPreparation | #QuizTime | #LearningTools | #Education | #StudentSupport Examify | Smart Grades | Latest update the most rigorous of all studies always involve testing a prediction by manipulating an independent variable and measuring the effect on a dependent variable - purpose is to test for causality To determine causality, one must show Concomitant variation - that manipulation of the independent variable is associated with the changes in the dependent variable Time Factor/chronology - independent variable precedes the change in dependent variable Alternate operating variables - refer to observed changes caused by extraneous or unknown variables *the relationship cannot be explained by another variable Threats to internal and external validity history/ historical events maturatio
