Discuss the impact of each scale of measurement on the ability or inability to be utilized on a test being standardized as a norm-referenced or criterion-referenced assessment. For the purpose of this discussion, you may cluster the ordinal and interval scale together. Subsequently, your post will include the following four elements: Ordinal or interval scale of measurement and norm-referenced test. Ordinal or interval scale of measurement and criterion-referenced test. Ratio scale of measurement and norm-referenced test. Ratio scale of measurement and criterion-referenced test. In your post: Provide at least one example that is not in your Psychological Testing and Assessment text for each combination above and describe how the referencing data would be collected. According to Cohen & Swerdlik(2018), measurement is defined as the act of assigning numbers/symbols to characteristics of things according to rules. Scale is also a set of numbers/symbols whose properties model empirical properties of the numbers that were assigned, the most common scale being a bathroom scale (Cohen & Swerdlik 2018). There are typically four common scales of measurements, which are nominal, ordinal, interval and ratio (Cohen & Swerdlik 2018). Nominal scale involves categorization with certain characteristics, Ordinal scale is the same with the addition of ranking the categories (Cohen & Swerdlik 2018). Interval scale is the same as ordinal scale with the addition of equal intervals between the numbers but still no absolute zero. The last scale is ratio which is like the ordinal with a true zero points (Cohen & Swerdlik 2018).

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
