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 method and instrument used in human services, and managerial research (UOPX, 2013).
Types of Reliability
Reliability is described as the degree to which a survey, test, instrument, observation, or measurement course of action generating equivalent ending each time an examiner performed the experiment. This process consists of five types, “alternate-form, internal-consistency, item-to-item, judge-to-judge, and test-retest reliability” (Rosnow & Rosenthal, 2008, p. 125). Alternate-form reliability is the degree of coefficient of relationship of different forms of the same experiment. Internal-consistency is the notion of how dependable the experiment is to the moderator approach of assessing the result of the test. Item-to-item is the consistency of a specific point on average. Judge-to-judge is the reliability result from a moderator on average Test-retest reliability is the degree of stability pertaining to the measuring instrument or the experiment involves providing reassurance to the result of the test (Reshow & Rosenthal, 2008).
Each of the type of reliability listed above is commonly use in research connected to human services. Because human services work primarily related to the core influence of helping an individual with lifestyle modification process; it is vital that researcher make certain that the experiment use to establish the theories for this practice is reliable. Let’s elaborate on test-retest reliability assesses consistency across
