Scales of Measurement
This week, you were introduced to four scales of measurement, easily remembered with the acronym NOIR, and include:
Part I: Scales of Measurement and Referencing
-Provide at least one example of a psychological construct or attribute that can be measured in your specialization or a related profession for each scale of measurement (nominal, ordinal, interval, and ratio) that is not in your Psychological Testing and Assessment text.
-Provide at least one example of a psychological construct or attribute that can be measured in your specialization for each type of referencing (norm-referenced and criterion-referenced).
-Provide a statement that evaluates which scale of measurement appears to be the most useful for examining attributes in your specialization or a related profession. Explain why it is the most useful.
-Evaluate which method of referencing (norm or criterion) appears to be the most useful for examining attributes in your specialization or a related profession. Explain your decision based on the area of focus regarding the test results. For example, identify if it is preferable to focus on how one individual performs relative to others who took the same test, or if it is preferable to only focus on what the individual can or cannot do.
Part II: Norms
-Explain the different types of norms and the sampling procedures used when developing norms for a standardized test.
-Identify one use and one limitation for each type of norm.
When designing a treatment plan, it is important to consider the client’s environment and preferences. For this discussion, provide examples of how you may need to adjust a behavior plan to address preferences or environmental constraints. Describe some ways you might attempt to determine client preferences and environmental constraints that could affect your plan.
