Plan the first goal. What you want to investigate is the target. If you say, I want to know what the cucumber market is like. This goal is the same as nothing! Goals must be subdivided and can be expressed and quantified by data. For example, I want to know the local purchase price curve, wholesale price curve, retail price curve, retail price curve, sales quantity, inventory quantity, local output and farmland price fluctuation curve, foreign entry quantity and price ratio and curve, retail quantity and wholesale quantity and their price trend and fluctuation range from February 20 16 to February 5. If we go deeper: the direction and quantity ratio of cucumber outflow in the wholesale market; Collect and compare the market size and cucumber sales data, the average frequency and quantity of cucumbers purchased by families, the average frequency and quantity of cucumbers purchased by canteens and the average frequency and quantity of cucumbers purchased by restaurants; The average shelf life and daily average loss rate of stored cucumbers can be dug endlessly. However, you need not be afraid. The choice of these data is related to what you want to do. So you should choose the relevant data survey according to the purpose of the survey.
Start tabulation after confirming the data requirements. But remember, tabulation must stand from the perspective of the interviewee. Try to condense all data into no more than 10 questions, and 10 questions involve the most basic root data. The method of asking questions should not be tendentious, and the words of asking questions should not have a turning point. It must be simple and unambiguous, and no culture can understand it at once. If the respondent only takes three minutes to complete the survey and reports the data he has memorized without thinking, the form will be passed.
Then determine the sample of the investigated population. It should be noted here that the accuracy of the survey results has nothing to do with the number of samples, but with the distribution of samples. Take a chestnut as an example: You should investigate the distribution of the retail price curve of cucumber on a certain day. You can't ask all the vegetable stalls in the local market. Only by sample collection. At this time, do you know how many local commercial organizations can sell vegetables? How many farmers' markets are there? How many fresh food stores are there? How many supermarkets are there? How many are there in the city center? What are distributed in residential areas? What are distributed in the urban-rural fringe? What is the estimated number of people who need services? Then, you should choose 4-5 commercial organizations according to geographical distribution, 4-5 according to different types, 4-5 according to large, medium and small scale, and then merge the overlapping commercial organizations, and you will have 20-30 appointment respondents. In this way, the survey data will be more accurate.
When entering a specific business organization, we should also pay attention to the selection of individual samples, such as farmers' markets, and ask good, ordinary and bad stall owners. Vendors who set up stalls all day only in the morning market should also ask about the price and sales of cucumbers in the morning and the price and sales at night ... in short, this means that it depends on you.
With the form and target group, you can start working now. If it is a survey with strong effectiveness, there must be a team, and everyone can work together in Qi Xin. It is cheaper to invite some students to do social practice, but it is necessary to make a sample return visit to prevent disorderly handing in papers. This is a matter of team management, and it won't happen again. If the effectiveness is not strong and you are not willing to spend money, run by yourself.
However, respondents are unwilling to cooperate and refusal is common. In order to improve their cooperation, it is necessary for you to find an identity for yourself. The simplest thing is to go to the local government department to open a letter of introduction and find a way by yourself. For example, you are entrusted by a large (famous) vegetable-related enterprise in xxx to do a survey in the local area, hoping to get the support of the government. Then take this letter of introduction to the farmer's market management office and the supermarket office. If they help you, the efficiency will be very high and the quality of the answers will be very good. If you can't get support, you have the cheek to ask for help one by one.
When you finish the booking survey, start another summary table, summarize all the data, and start statistics according to your needs. Work out the data and draw a picture, and you can start the analysis. This survey ended perfectly!
Very troublesome. If you really want to do it, it is more convenient to find a research company.
