How does technology help in collecting data for survey?4 answersTechnology plays a crucial role in enhancing data collection for surveys. GPS-assisted methods, such as smartphone-based tracking and prompted-recall data collection, offer improved accuracy and detailed insights into individuals' travel behavior. Additionally, the use of internet analysis technology enables efficient data analysis, providing valuable insights into student attitudes towards educational programs. Moreover, the implementation of a survey system utilizing geo-fenced communication protocols on mobile devices ensures real-time customer feedback for service ratings. Furthermore, technology aids in questionnaire creation and data collection by utilizing web crawlers to extract and organize questionnaires into databases, facilitating research studies and analysis of results. Overall, technology streamlines the data collection process, enhances accuracy, and enables real-time feedback, benefiting various fields from education to customer service.
How does computer assistance help in collecting data for survey?4 answersComputer assistance significantly enhances data collection for surveys by enabling efficient processes at various stages. Computer-Assisted Interviewing (CAI) software, commonly used in government surveys, allows for real-time modifications during fieldwork and post-data collection stages, ensuring higher data quality and quicker public data file availability. In clinical research, methods like audio computer-assisted self-interviewing (A-CASI) and telephone A-CASI improve patient-reported data collection, especially in postmarketing studies, offering advantages in data management efficiency. Additionally, computer-aided personal interviewing (CAPI) in developing countries aids in obtaining high-quality data by facilitating complex skip patterns, GPS technology for sampling accuracy, real-time data quality checks, and interviewer monitoring, despite challenges like software learning costs and ethical considerations. These technologies streamline data collection, enhance accuracy, and expedite analysis in diverse survey settings.
Why use surveys to collect data?5 answersSurveys are utilized to collect data due to their versatility in evaluating items, products, employee/customer satisfaction, and aiding research studies. However, challenges like errors in survey data due to various factors exist, emphasizing the importance of ensuring data quality. The precision and accuracy of survey results heavily rely on the representativeness of the sample population, as non-random samples can lead to biased estimates. Ethical considerations are also crucial when conducting surveys to maintain scientific rigor, emphasizing informed consent and scientific integrity in research practices. In essence, surveys serve as valuable tools for gathering information, but meticulous attention to detail is essential to mitigate errors, ensure data quality, and uphold ethical standards in research endeavors.
How to treat survey response data in statistics?5 answersSurvey response data in statistics can be treated using various methods. One common approach is to use ordinal regression models, which can provide probability estimates for all response categories and yield information about the full response scale rather than just the mean. Another method is the double-transform-both-sides (DTBS) approach, which applies a Box-Cox type transformation to both the outcome and regression function to estimate median regression parameters for highly skewed response variables. Additionally, missing data in surveys can be handled using weighting methods, such as propensity score adjustment, which compensates for nonresponse by using response probability. Imputation methods can also be used to create complete data for statistical estimation or inference of the missing data. Finally, the Rasch probabilistic measurement model can be employed to examine the quality of survey response data, identifying inappropriate survey items and enhancing the quality of items and persons through fit statistics and misfit response strings.
Why we use survey methods?5 answersSurvey methods are commonly used in social sciences research to gain information about large populations, measure public attitudes and orientations, and answer specific questions. Surveys provide a cost-effective and time-efficient way to gain insight into the attitudes, thoughts, and opinions of populations. They can be used to measure deliberation and its impact, draw proper samples, measure complex concepts, ensure statistical power, and conduct longitudinal analysis. Surveys also allow researchers to generalize findings from a sample of respondents to a population, quantify qualitative research, and assist in policymaking. The flexibility of survey research designs and data collection instruments allows researchers to choose methods that work best for their study. However, it is important to consider the motivation of respondents, openness of researchers, low response rates, limitations of online surveys, and the need for clear and objective reporting guidelines.
What are the advantages and disadvantages of social surveys?3 answersSocial surveys have several advantages and disadvantages. One major advantage is that surveys provide an economical access to participants online, making it easier to gather data from a large sample of respondents. Surveys also allow researchers to generalize their findings from a sample to a larger population, making them useful for policymaking and informing public policy. However, a major disadvantage of survey research is the low response rates, which can limit the representativeness of the sample. Additionally, surveys may reinforce existing world views, power relations, and a narrow construction of social issues, potentially limiting the capture of the complexities of everyday life. Despite these limitations, surveys remain an important tool for measuring opinions, attitudes, and behaviors that are not available in archival records.
