bet365 Play online games Social survey is one of the main sources of key data of the community and the country。According to the official website of the University of Pennsylvania, the official website of the University of Pennsylvania, recently reported，The school's communication and political professor Kathleen Hall Jamieson and others posted a post.，In the era of rapid development of information technology，How to ensure the accuracy and authority of social surveys is a major challenge facing scholars。

Social survey application wide，For example, provide reference information for policy makers、Clarifying the needs of stakeholders、Improve the accountability system or customer service of the private and public sector、Improve the quality of life of the people。bet365 Play online games In recent years，More and more Americans are skeptical of social surveys as reliable as before。Researchers observed，The proportion of Volkswagen's refusal to participate in the survey continues to rise。decades ago，Researchers can contact most American adults through a fixed telephone。Americans at that time rarely received social survey invitations，Therefore, most people will readily accept the investigation request。Contemporary society that replaces fixed telephones on mobile phones，Many people take the initiative to avoid answering strange calls。The person who answered the phone finally agreed that the possibility of interviewing was much smaller than in the past。So，Assume that the target population may participate in the survey or no more。Jenmison and others think，Social changes brought about by the development of science and technology，If the researchers cannot bet365 best casino games master the population statistics information of the participants，will reduce the accuracy of the survey，Impact survey results。

Jenmison and others also found，The decline in the response rate of the survey increased the cost and difficulty of researchers to obtain the most representative sample types。Former，Researchers need to extract more than 60%of the survey reply from the target sample，and the current response rate rarely exceeds 10%。other，Americans have gradually decreased by Americans' trust in government and media institutions that have funded major investigations。deliberately destroying scholars' remarks、Disciplinary information and other behaviors，It deepen the doubts of the US public about the results of the investigation。

During the epidemic period，The accuracy of public opinion surveys and the public reputation crisis has aroused close attention in the American academic Bet365 lotto review community。At a online meeting on November 18, 2021，President of the National Academy of Sciences Massia McNart calls on scholars to strengthen the integrity of maintenance survey and research，Improve the limitations and advantages of the investigation，Further disclosure information about the evaluation of the survey results，Guide the public to identify the significant features of credible investigations。Jenmison and others think，High -quality to complete these initiatives also need to investigate researchers to practice three scientific specifications: transparency、clarity and correction records。First，Researchers should publicly investigate，Including sampling design、Research model、Weighted analysis and interviewee identity, etc.，It is convenient for other scholars to put forward constructive opinions。A survey with high transparency not only has higher reclaimability，bet365 live casino games It is also conducive to the survey method of scholars comparing different results。Second，To improve the clarity of the survey，Scholars need to use accurate terms to express the academic method of survey、Research objects and factors that may affect the accuracy of the investigation。Last，Scholars should build an open database，Recording technical issues and remedial measures，Promoting the scientific self -correction mechanism。But，To make the "Correction Record" database function in maintaining the integrity of maintenance survey，Can't do without the experts carefully mark various problems，Evaluate the feasibility of the proposed solution，Determine the implementation effect of the solution。

Jenmison and others have called on major academic and investigating agencies to continue to reflect and make progress during the investigation。The American academic community bet365 Play online games needs a cultural change，Make more comprehensive、More openly disclosed the investigation practice and its limitations become the norm。
