Psychological assessment scale refers to a continuum of numbers that can quantify the characteristics of things. Different scales have different units and reference points, and different scales are prepared. Different scales have different measurement levels and their measurement accuracy is also different. Psychological evaluation scale refers to a measurement method that uses a specially designed measurement table to quantify the psychological test.

At present, there are two or three hundred psychological tests and psychological scales for psychological measurement. However, there are only a dozen or more commonly used in clinical and psychological counseling work. However, many of these commonly used scales are not disclosed to non-professionals, and they need to spend hundreds or even thousands of dollars to participate in their training before they are eligible to purchase. There are places that are not easy to find. For non-professional research and study of psychology, more than 100 commonly used psychological test scales and test tools at home and abroad are optimized and selected, and some tests and scales often used in psychological counseling are compiled into a computer * * Or measurement scale, which we often say is a common psychological measurement scale.

1. Psychological assessment ratio scale

(1) Definition

Ratio scales are scales that have categories, grades, isometric features, and absolute zeros.

(2) Features

The ratio scale is the highest level of measurement scale. Its data can be used for addition, subtraction and multiplication.

(3) Suitable statistical methods

In addition to the statistical methods suitable for equidistant scales, the statistical methods suitable for statistical analysis of ratio scales also include geometric mean and coefficient of variation.

2. Psychological Assessment Order Scale

(1) Definition

Sequential scale refers to a scale that arranges numbers according to the size, grade, and degree of things. It can not only refer to the category of things, but also can indicate the size, grade, or degree of things in different categories.

(2) Features

Sequential scale is the second-lowest level of measurement scale. It does not represent the true quantity of an object's characteristics, nor does it represent an absolute value, so it cannot perform algebraic calculations.

(3) Suitable statistical methods

The statistical methods suitable for statistical analysis of ordinal scales are-median, percentile, rank correlation coefficient and Kendall's harmony coefficient.

3. Psychological assessment named scale

(1) Definition

A named scale refers to a scale that uses numbers to represent things or classifies things with numbers. The numbers at this time are just symbols of things, without any amount of meaning.

(2) Features

The named scale is the lowest level of measuring scale, and it can be subdivided into two forms: the first is the named scale, which refers to individual things by numbers. The second is the category scale, which refers to the type of things with numbers.

(3) Suitable statistical methods

The statistical methods suitable for statistical analysis of named scales are-percentage, frequency, mode, and 2 test.

4. Psychological assessment isometric scale

(1) Definition

Isometric scale refers to a scale that can not only refer to the category and level of things, but also have equal units.

(2) Features

Isometric scales are higher-level measurement scales. The number of the equidistant scale is a real quantity, and the units of its various parts are equal, so it can be added and subtracted. The equidistance scale does not have an absolute zero, and its zero is the relative zero that people assume. Therefore, the two quantities in the equidistant scale cannot be multiplied and divided, that is, there is no multiple relationship between the data.

(3) Suitable statistical methods

The statistical methods suitable for the statistical analysis of the isometric scale are: average, standard deviation, correlation coefficient of product difference, and t-test and f-test.
