The data collected from sentence completion tests can usually be analyzed either quantitatively or qualitatively. [4] Usually, sentence completion tests can be interpreted in two different ways: subjective-intuitive analysis of the underlying motivations projected in the subject's responses, or objective analysis by means of scores assigned to ...
A common method is to "research backwards" in building a questionnaire by first determining the information sought (i.e., Brand A is more/less preferred by x% of the sample vs. Brand B, and y% vs. Brand C), then being certain to ask all the needed questions to obtain the metrics for the report. Unneeded questions should be avoided, as they are ...

Semi-structured data are increasingly occurring since the advent of the Internet where full-text documents and databases are not the only forms of data anymore, and ...
A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model.

Structured interviews are a means of collecting data for a statistical survey. In this case, the data is collected by an interviewer rather than through a self-administered questionnaire. Interviewers read the questions exactly as they appear on the survey questionnaire. The choice of answers to the questions is often fixed (close-ended) in ...
Document-oriented databases have been developed for storing, retrieving, and managing document-oriented information, also known as semi-structured data. Extensible Markup Language ( XML ) is a World Wide Web Consortium ( W3C ) Recommendation setting forth rules for encoding documents in a format that is both human-readable and machine-readable.
Positional Analysis Questionnaire was developed with the hope that it could be used with a minimum of training on the part of the individual analyzing a job. [2] Compared to many other methods in job analysis, PAQ has been found to be effective, inexpensive, and easy to use for human resource and trainees. Its purpose is to define the duties ...
A structured document is an electronic document where some method of markup is used to identify the whole and parts of the document as having various meanings beyond their formatting. For example, a structured document might identify a certain portion as a "chapter title" (or "code sample" or "quatrain") rather than as "Helvetica bold 24" or ...
