Finally, physiological measures are those that involve recording any of a wide variety of physiological processes, including heart rate and blood pressure, galvanic skin response, hormone levels, and electrical activity and blood flow in the brain. Such a claim would depend on an arbitrary decision about where to “start” the temperature scale, namely, what temperature to call zero (whereas the claim is intended to make a more fundamental assertion about the underlying physical reality). Ordinal scales indicate the order of the data according to some criterion.

Perhaps the most common measure of internal consistency used by researchers in psychology is a statistic called Cronbach’s α (the Greek letter alpha). Distinguish the four levels of measurement, give examples of each, and explain why this distinction is important. To provide such knowledge, we surveyed a random sample of 200 journal articles in the PsycINFO database coding for psychological content area, research design, measurement … Zero degrees Fahrenheit does not represent the complete absence of temperature (the absence of any molecular kinetic energy). Measurement, the process of associating numbers with physical quantities and phenomena. The various measures of stress, for example, are all correlated with each other and have all been shown to be correlated with other variables such as immune system functioning (also measured in a variety of ways) (Segerstrom & Miller, 2004)[3].
