Psychological testing is important to many areas of the field of psychology. First of all psychological testing helps in placement decisions, treatment planning, diagnosing and so forth. So what is psychological testing? Psychological testing is comprised of tests such as intelligence test such as the WAIS-IV (Wechsler Adult Intelligence Test-Fourth Edition) and the WISC-IV (Wechsler Intelligence Scale for Children-Fourth Edition) and other tests that are considered culturally fair or those with special disabilities or considered to be a special population (Groth-Marnat, 2003). Other psychological testing includes those tests that help identify if there are any personality patterns that may be of interest to a treating clinician or perhaps for employment. Such tests of personality are the MMPI-II (Minnesota Multiphasic Personality Inventory) or the Beck Depression Inventory that helps identify if a person is suffering from depression and if so what level of depression (Groth-Marnat). All this information is useful; however, it is not intended to be used as a sole method of evaluation. Psychological testing is but one mere component of gathering data to form a clinical picture of the person being tested/evaluated. The clinical interviews, interview with family/friends/teachers, medical records, behavior records and so on all help to decide what can be derived from each of these tests that is in the best interest of the client (Sattler & Hodge, 2006). After all psychological testing, therapy and so forth is all supposed to be done with high ethical standards and with the best interest of the client in mind at all times (Fisher, 2003).References Fisher, C.

There are different units for measuring different characteristics: mass, weight, length, area, volume, temperature and so on.
They are scales for measuring temperature.
They are measuring two different things.

the measurement must be taken following a 12 hour rest, following sleep, during no psychological or physical activity, in an ambient constant temperature.
An electronic measuring instrument which produces a display showing the relationship of two or more variables.
Coordinate measuring machines (CMMs) are precision measurement devices used to determine the geometric characteristics of an object by measuring its dimensions and orientation. They use a probe to collect data points that are then analyzed to create accurate representations of the object's shape. CMMs are commonly used in industries such as manufacturing, aerospace, and automotive for quality control and inspection purposes.
