Web Survey
With the application of probability sampling in the 1930s, surveys became a standard tool for empirical research in social sciences, marketing, and official statistics. The methods involved in survey data collection are any of a number of ways in which data can be collected for a statistical survey. These are methods that are used to collect information from a sample of individuals in a systematic way. First there was the change from traditional paper-and-pencil interviewing (PAPI) to computer-assisted interviewing (CAI). Now, face-to-face surveys (CAPI), telephone surveys ( CATI), and mail surveys (CASI, CSAQ) are increasingly replaced by web surveys. Modes of data collection There are several ways of administering a survey. Within a survey, different methods can be used for different parts. For example, interviewer administration can be used for general topics but self-administration for sensitive topics. The choice between administration modes is influenced by several factors, ...

Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determine if ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Custom Online Panel
A custom online panel or Internet access panel is a group of pre-screened respondents who have expressed a willingness to participate in surveys and/or customer feedback sessions. The custom online panel is also known as a customer advisory panel, proprietary panel or an online research panel. Respondents become "panelists" by completing a profiling questionnaire. The data collected includes demographics, lifestyle characteristics and media habits, which provides a basis for future survey participation. Form and process A panel can range in size from 100 to 100,000 or more people. Larger panels can enable surveys of smaller target groups. Panel quality is not determined solely by size, however, and how panel members have been sourced is also important. Panels can provide a dedicated group that market researchers can engage with and learn from over time. At a moment’s notice researchers can investigate the attitudes, behaviour and opinions of existing or potential customers ...

Computer Assisted Telephone Interviewing
Computer-assisted telephone interviewing (CATI) is a telephone surveying technique in which the interviewer follows a script provided by a software application. It is a structured system of microdata collection by telephone that speeds up the collection and editing of microdata and also permits the interviewer to educate the respondents on the importance of timely and accurate data. The software is able to customize the flow of the questionnaire based on the answers provided, as well as information already known about the participant. It is used in B2B services and corporate sales. CATI may function in the following manner: * A computerized questionnaire is administered to respondents over the telephone. * The interviewer sits in front of a computer screen. * Upon command, the computer dials the telephone number to be called. * When contact is made, the interviewer reads the questions posed on the computer screen and records the respondent's answers directly into the computer. * ...

Sampling Frame
In statistics, a sampling frame is the source material or device from which a sample is drawn. It is a list of all those within a population who can be sampled, and may include individuals, households or institutions. Importance of the sampling frame is stressed by Jessen and Salant and Dillman.Salant, Priscilla, and Don A. Dillman. "How to Conduct your own Survey: Leading professional give you proven techniques for getting reliable results" (1995) Obtaining and organizing a sampling frame In the most straightforward cases, such as when dealing with a batch of material from a production run, or using a census, it is possible to identify and measure every single item in the population and to include any one of them in our sample; this is known as ''direct element sampling''. However, in many other cases this is not possible; either because it is cost-prohibitive (reaching every citizen of a country) or impossible (reaching all humans alive). Having established the frame, there ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Response Rate (survey)
In survey research, response rate, also known as completion rate or return rate, is the number of people who answered the survey divided by the number of people in the sample. It is usually expressed in the form of a percentage. The term is also used in direct marketing to refer to the number of people who responded to an offer. The general consensus in academic surveys is to choose one of thsix definitions summarized by the American Association for Public Opinion Research(AAPOR). These definitions are endorsed by the National Research Council and the Journal of the American Medical Association, among other well recognized institutions. They are: # Response Rate 1 (RR1) – or the minimum response rate, is the number of complete interviews divided by the number of interviews (complete plus partial) plus the number of non-interviews (refusal and break-off plus non-contacts plus others) plus all cases of unknown eligibility (unknown if housing unit, plus unknown, other). # Response ...

European Social Survey
The European Social Survey (ESS) is a social scientific endeavour to map the attitudes, beliefs and behaviour patterns of the various populations in Europe. ESS is listed in the Registry of Research Data Repositories re3data.org. Prof Rory Fitzgerald is the Director of the ESS which in 2013 became a European Research Infrastructure Consortium. The headquarters are at City, University of London. History The ESS was initiated by the European Science Foundation. One of the reasons to start this new time series of social scientific data was that existing cross-national attitude surveys were regarded as not of sufficient methodological rigour to draw on as reliable sources for knowledge about changes over time in Europe. Starting in 2002 the survey has been held every two years in many European countries, with round 6 (2012) covering 30 nations. In 2013 the ESS became an independent legal entity known as an ERIC and as of 2020 has 25 Member countries and one Observer country. In 2016 ...

Multitrait-multimethod Matrix
The multitrait-multimethod (MTMM) matrix is an approach to examining construct validity developed by Campbell and Fiske (1959). It organizes convergent and discriminant validity evidence for comparison of how a measure relates to other measures. The conceptual approach has influenced experimental design and measurement theory in psychology, including applications in structural equation models. Definitions and key components Multiple traits are used in this approach to examine (a) similar or (b) dissimilar traits ( constructs), in order to establish convergent and discriminant validity between traits. Similarly, multiple methods are used in this approach to examine the differential effects (or lack thereof) caused by method specific variance. Scores could be correlated because they measure similar traits, or because they are based on similar methods, or both. When variables that are supposed to measure different constructs show a high correlation because they based on similar m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ESOMAR
ESOMAR is a membership organization for market, social, and opinion researchers that was founded in 1947. The name ESOMAR is an abbreviation of their original name, the European Society for Opinion and Marketing Research, which reflects the original catchment of the organisation. ESOMAR has published an ethics and guidance code for its members since 1948, with a joint code being published with the International Chamber of Commerce (ICC) since 1977. History ESOMAR was founded in 1947. In 1948 the first version of code of practice for members was published. In 1976 ESOMAR and the ICC determined a single code of practice would be preferable and the first joint code of practice was published in 1977, with revisions in 1986, 1994 and 2007. From the revision in 2016 the title and content was changed to include data analytics. Activities ESOMAR produces information about market research.

Empirical Research
Empirical research is research using empirical evidence. It is also a way of gaining knowledge by means of direct and indirect observation or experience. Empiricism values some research more than other kinds. Empirical evidence (the record of one's direct observations or experiences) can be analyzed quantitatively or qualitatively. Quantifying the evidence or making sense of it in qualitative form, a researcher can answer empirical questions, which should be clearly defined and answerable with the evidence collected (usually called data). Research design varies by field and by the question being investigated. Many researchers combine qualitative and quantitative forms of analysis to better answer questions that cannot be studied in laboratory settings, particularly in the social sciences and in education. In some fields, quantitative research may begin with a research question (e.g., "Does listening to vocal music during the learning of a word list have an effect on later memory ...
