What is the general effective questionnaire rate?

Question 1: What is the recovery rate of the questionnaire survey? Is the recovery rate important? I sent out 654.38+million questionnaires, and recovered 654.38+million questionnaires, with a recovery rate of 10%.

You sent out 50 questionnaires, and 50 of them were recovered, with a recovery rate of 100%.

It would be nice if the collected questionnaires were enough to conduct a sampling survey on the needs of pregnant women.

Mainly depends on the efficiency of the questionnaire. If the identifiable efficiency of the questionnaire is less than 90%, it means that there is something wrong with our adjustment method and the research data will lose its value.

Question 2: What is the recovery rate of the questionnaire? Recovery rate = (number of cases actually completed/total number of cases planned to be completed) × 100% What are the standards for acceptable recovery rate and good recovery rate? At present, there is no unified understanding in academic circles. Nak Mias et al. pointed out: "It is not easy to determine an acceptable response rate standard, because scientists have differences on the minimum response rate standard" (Nachmias &；; Nak Mias, 2000: 2 13). American sociologist Bobby put forward a simple hierarchical rule: "For analysis and report writing, a questionnaire recovery rate of at least 50% is enough, and a recovery rate of at least 60% is good; And reaching 70% is very good. " But he also pointed out clearly: "Remember, the above data are only rough indicators, and there is no statistical basis" (Bobby, 2000: 33 1). See more answers "";

Question 3: What is the effect of the questionnaire? 90%

Question 4: How to calculate the validity of the questionnaire? A total of 840 questionnaires were distributed, 820 were recovered and 800 were valid. How efficient is the questionnaire? Questionnaire recovery rate = actual number of questionnaires recovered/number of questionnaires sent, that is, 820/840.

Questionnaire Efficiency (Degree) = (Actual number of returned questionnaires-invalid answers)/Actual number of returned questionnaires 800/820.

Question 5: What is the recovery rate of the questionnaire survey? According to the general survey, if there are more than 100 questionnaires, more than 40% of the questionnaires are valid.

Question 6: What is the maximum non-response rate allowed during the questionnaire survey? The non-response rate should be viewed from many aspects.

1, the non-response rate caused by the investigation method and process has no influence on the accuracy.

2. The non-response rate of survey items, that is, the non-response rate caused by questionnaire questions, reflects the unreasonable investigation plan, preparation and setting.

Generally speaking, the unanswered rate reflects the situation of question setting, which affects the reputation of the accuracy of the results.

However, if the non-response rate is high, it indicates that there is something wrong with the survey setup, and it also reflects the one-sided tendency of the survey results.

Finally, if it is 1 above, the non-response rate is low, which will not affect the accuracy of the survey.

If it is 2, the highest non-response rate cannot be higher than 40%, otherwise it is not representative.

Question 7: What are the types and characteristics of questions in the questionnaire? The types of questionnaires can be divided from different angles. According to the answers to the questions, it can be divided into three types: structured, semi-structured and open; According to the survey method, it can be divided into interview questionnaire and self-filled questionnaire; According to the purpose of the questionnaire, it is divided into screening questionnaire, questionnaire and return visit questionnaire. First of all, according to the answer to the question. Questionnaire can be divided into three basic types: structured, open and semi-structured. 1. structural formula. It is also commonly known as closing the door or closing the door. The answer to this questionnaire has been determined by the researcher on the questionnaire. It is enough for the respondent to carefully select an answer and circle or tick it. 2. open it. Also known as open. There is no fixed answer in this sentence test paper, so that returnees can play freely. 3. Semi-structural structure. This kind of questionnaire is between structured and open. There are both fixed and standard answers to questions, and some answers are free for respondents to give full play to their advantages. This kind of questionnaire is widely used in actual investigation. Second, according to the survey method. According to the survey methods, questionnaires can be divided into: self-filled questionnaires and interview questionnaires. Self-administered questionnaire is a questionnaire filled and answered by the respondents themselves. Interview questionnaire is a questionnaire that the interviewer interviews through interviews and is answered by the interviewer. Due to the different sending methods, self-filled questionnaires can be divided into two categories: sending questionnaires and mailing questionnaires. Sending questionnaires is a form of investigation in which investigators directly send questionnaires to respondents and the investigators directly withdraw the questionnaires. The mailing questionnaire is a survey form in which the respondents are directly mailed by the survey unit, and the respondents fill in the answers themselves and send them back to the survey unit. The characteristics of these survey forms are: interview questionnaires have the highest recovery rate and the most reliable results, but they are costly and time-consuming, and the recovery rate of such indirect papers is generally above 90%; The sending of inter-paper and the collection of character strings are low, and the investigation process cannot be controlled, so the credibility and effectiveness are low. Moreover, due to the low recovery rate, the sample will be biased, which will affect the report of the sample to the whole population. Generally speaking, the recovery rate of mailing questionnaires is about 50%; The advantages and disadvantages of sending a self-filled questionnaire are between the above two, and the recovery rate is required to be above 67%. Third, according to the purpose of the questionnaire. Generally speaking, questionnaire survey, especially market survey, includes three types of questionnaires, namely screening questionnaire, questionnaire and return visit questionnaire (review questionnaire). 1. Screening questionnaire. The screening questionnaire is a set of questions to ensure that the respondents in the survey are indeed the target consumer groups of the products. Generally, it includes five aspects: the exclusion of individual natural state variables, the exclusion of product applicability, the exclusion of product use frequency, the exclusion of States that have special influence on product evaluation and the exclusion of investigation refusal. (1) Exclude individual natural states. The exclusion of personal natural state is mainly to identify whether the natural state of the interviewee conforms to the target market of the product. The main natural state variables include age, gender, education level and income. We take the screening amount of high-end cosmetics market survey as an example to illustrate that it is not suitable for the exclusion of personal natural state. ● Age discrimination. Cosmetics used in China have obvious age tendency, and young people and old people should be excluded. Therefore, the age screening question is designed as follows: Your age is below 18, stop visiting L 8-45, and continue visiting people over 45 ● Gender screening. Suppose this product is only designed for women. The screening question is: Your gender: Men stop visiting women and continue income screening. In China, there are two factors that affect women's purchase of cosmetics, namely personal income and total household income. Therefore, the screening of income includes two aspects: your personal monthly income (including salary, bonus, second job income, etc. ) is 1500 yuan and above. Stop visiting your family after 1500 yuan. Your family's total monthly income is 3,000 yuan or more, and the visit will be suspended after 3,000 yuan. (2) Eliminate product applicability. Assuming that this cosmetic is only suitable for oily and mixed skin, the design of the product applicability screening question is as follows: ● Your skin is oily and mixed skin, and the visit is neutral; (3) Eliminate the frequency of product use as appropriate. Obviously, if the rate is too low, it cannot be the target of product investigation. The screening questions are designed as follows: ● How often do you use cosmetics? There is little need to stop visiting once a month or less. (4) Eliminate the state that has special influence on product evaluation. This kind of platoon ";

Question 8: What is the recovery rate of valid questionnaires? Over 80%
