What are the methods of investigation?

1, data method

Data method is to collect, analyze and sort out the relevant information of business activities through various channels. This method is both cheap and effective.

2. Query method

Inquiry method is a means to collect information by way of inquiry, in which the investigated matters are asked in person or by telephone or in written form to obtain the required information. Inquiry is a common method in market research.

Inquiry methods can be divided into individual inquiry, group inquiry, telephone inquiry, letter inquiry and e-mail inquiry according to different investigation methods. The adoption of these methods depends on the nature and requirements of the investigation questions, the scope of information, the investigation funds and the length of time.

3. Observation method

Observation is an observation method that is not felt by the respondents. This method does not directly ask questions to the respondents, but observes and records the facts from the side and observes the behaviors and attitudes of the respondents.

For example, investigators observe the behavior of customers on the spot. This method can collect data objectively, and the survey results are close to reality, but it needs experienced investigators.

4. Experimental method

Experimental method is to choose a specific market and time to carry out a small-scale experiment, and then analyze it to see if it is worth popularizing on a large scale. Experimental methods are widely used, whenever the product changes varieties, prices, quality, specifications, colors, packaging and other factors.

You can use experimental methods. Through experiments, we can know whether consumers accept this price and whether the varieties of colors are popular, so as to decide whether to produce and how much to produce.

5. Sampling method

It is best to obtain enterprise survey data through a comprehensive survey. The data obtained by this method is comprehensive and reliable, but it consumes a lot of manpower, material resources and financial resources, and the investigation time is long, which is not suitable for the requirements of general enterprises.

Enterprises can choose sampling methods under the conditions of many varieties, large output, many users and wide sales range. That is to say, select some representative objects from all the survey objects to investigate, and infer all the survey methods from the quantity accordingly.

Sampling survey is not only economical, labor-saving and time-saving, but also can concentrate the survey objects on a few representative objects, and can obtain similar survey results as the comprehensive survey, so this method is widely used in the survey.
