Methods of obtaining information through investigation
1 observation method
Observation is a research method by which researchers obtain first-hand information by observing the activities of the respondents. In practice, researchers usually use ear-to-ear and eye-to-eye methods or use various video recording devices. Directly record the behavior or situation that is happening at the research site. Observation is an effective way to collect information. Compared with other methods, observation can avoid the feeling of being investigated, and the activities of the respondents are not interfered by external factors, thus improving the reliability of the survey results. However, on-site observation can only see the superficial phenomenon, but can not understand its internal factors and reasons, and when using observation method, it is necessary to observe repeatedly to get practical and credible results. At the same time, it also requires researchers to have certain professional ability to see the results.
2. Thematic discussion method
Thematic discussion refers to inviting 6- 10 people to spend several hours discussing a topic, such as a service or a design element, under the guidance of an experienced host. The host should keep an objective position, always create topics around the topic of this discussion, stimulate participants' creative thinking and speak freely, so that the quality of the host is higher. Conversation should be conducted in a relaxed environment, such as at home. By providing drinks, everyone will feel at ease, so as to gain a more natural and true point of view.
3. Query method
Inquiry method refers to collecting information through direct or indirect inquiry, which is a common field investigation method. There are various forms of inquiry, which can be divided into interview, telephone inquiry, email survey and indwelling questionnaire according to the different contact methods between researchers and respondents.
4. Experimental method
Experimental investigation is an effective means to study the causal relationship between various factors. By effectively controlling the experimental object, environment and experimental process, we can distinguish the mutual influence and influence degree among various factors, thus providing opinions and references for enterprise managers to make decisions.
5. Statistical survey? Make statistical tables, decompose elements, and fill in the summary in layers.
6. Comparative analysis method.
