How to use quantitative evaluation methods to select specific inquiry survey methods 20

Quantitative research is generally conducted to obtain statistical results on the population of a particular research subject. Qualitative research has the characteristics of exploratory, diagnostic and first-class nature, it does not pursue precise conclusions, but only understands the problem, finds out the situation, and draws perceptual understanding. The main methods of qualitative research include:

Group interviews with several people, in-depth interviews asking for detailed answers, and various projection techniques, etc. In quantitative research, information is expressed in some kind of number. When processing and analyzing these figures, it is first necessary to clarify the scale on which these information materials are measured and processed

s.Stevens divides scales into four types, namely nominal, sequential, spacing, and proportional scales.

Four measurement scales and characteristics for quantitative research.

A nominal scale is a numerical value used to indicate whether it belongs to the same person or thing.

The magnitude of the values used in the order scale corresponds to the specific order of the object of study. For example, the upper-middle, upper-middle, middle-lower, lower-middle, lower-middle, and lower-class social strata are labeled as "or"3 in this category. It's just that the difference between 5 and 4 and 4 and 4 and 4 and 3 and not necessarily the same.

Etc is an arbitrary symbol, and it doesn't hurt if it is written as .

The spacing scale uses a numerical value that indicates not only the amount of the measured objects, but also the degree of their size, i.e., the size of the interval. However, the fact that the origin in such a scale can be arbitrarily set does not mean that the quantity of the thing is "nothing". For example, O°C is an absolute temperature of 273°K and 32°F Fahrenheit.

The values of the nominal scale and the sequential scale cannot be added, subtracted, multiplied, and divided, but the values of the spacing scale can be added or subtracted. However, since the origin is arbitrary, multiplication and division cannot be performed. For example, the difference between 5 and 10 can be said to be the same as the difference between 15 and 20, both are 5°C.

But it can't be said that 20 is 4 times warmer than 5.

The meaning of the scale is absolute, i.e. it has the origin 0 of the quantity that means "nothing". Length, weight, time, etc., are all within the range of proportional scale measurements. The difference and ratio of the proportional scale measurements are all comparable.

For example, the difference between 5 minutes and 10 minutes and between 10 minutes and 15 minutes is 5 minutes, and 10 minutes is 5 times that of 2 minutes. Scale scales can be added, subtracted, multiplied, and divided.

There are three forms of test and evaluation of the validity of the survey methods and the obtained data: surface validity, quasi-test validity, and construct validity.

Examining and evaluating survey methods and the information obtained are part of the social survey and research methodology. Social investigation and research methods are a set of tools for observing and measuring social phenomena, a set of scientific methods for analyzing and using data on social phenomena, and a set of thinking logic and expression methods for scientific communication of phenomena of human production and life such as society, economy, education, politics, law, management, public health, and news reporting. It mainly includes science and social research, social science research and theory, social investigation and research methods, problem selection, and data acquisition.

Answer] :d experience method: use the existing intelligence and information, according to the experience of the relevant personnel, combined with the company's personnel needs.

Descriptive: The human resource planner can describe and make assumptions about the changes in the relevant factors of the organization in a certain period in the future. De Zana Fen Fi Fa:

Also known as the expert evaluation method, it generally uses questionnaire surveys to listen to the analysis and evaluation of the future human resources needs of enterprises by experts (especially personnel experts), and finally reach an agreement through repeated repetition. Conversion Ratio Method: The purpose is to convert the business volume of the enterprise into the demand for personnel, which is a method that meets the short-term needs**.

Answer]: a, b, c, d, e

The questionnaire survey evaluation method is mainly used for the investigation and evaluation of the training content, training courses, trainers, training venues, training materials and other main links in the training project, such as checking the matching degree between the training objectives and the work tasks, evaluating the application of the training content by the trainees in the work, understanding the learning methods preferred by the trainees, and understanding the attitude of the trainees towards the teaching methods used by the trainers.
