What are the ways to collect information?

Methods of collecting information include investigation, observation and experiment.

1, survey method

Investigation is one of the most commonly used methods in social science research. In order to achieve the envisaged purpose, the research method of making a plan to collect all kinds of information on a certain aspect of the research object comprehensively or relatively comprehensively, and analyzing and synthesizing it to draw a certain conclusion is the investigation method.

Its purpose can be to fully grasp the present situation, or to reveal the existing problems, find out the causes and consequences, and provide viewpoints and arguments for further research or decision-making.

Its advantage is that it can investigate multiple objects at the same time in a short time, obtain a large number of data, and quantify the data, which is economical and time-saving. Its main disadvantage is that candidates may give wrong or wrong answers for various reasons.

Investigation is one of the commonly used methods in scientific inquiry. When investigating, we should make clear the purpose and object of the investigation, make a reasonable investigation plan, record truthfully, sort out the analysis results, and sometimes use mathematical methods to make statistics. The commonly used survey methods are general survey and sampling.

2. Observation method

Observation method refers to a method in which researchers use their own senses and auxiliary tools to directly observe the research object according to a certain research purpose, research outline or observation table, so as to obtain information. Scientific observation is purposeful, planned, systematic and repeatable.

The common observation methods are checklist method; Grade scale method; Narrative description. Observation generally uses sensory organs such as eyes and ears to perceive the observed object. Due to the limitation of human sensory organs, observers often have to resort to various modern instruments and means, such as cameras, tape recorders, video recorders and so on. Assist in observation.

3. Experimental method

The experimental method is to conduct a small-scale experiment of marketing methods first. Then, analyze whether this practical marketing method is worth popularizing on a large scale. Its characteristic is to extract one or two factors from many factors that affect marketing, and observe and analyze their differences with marketing activities.
