Selection Ratio
Selection ratio refers to the ratio of the number of job positions to the number of job applicants and is used in the context of selection and recruitment. It is typically assumed to be a number between 0 and 1 where a number closer to zero implies that there are many applicants for any one position. Overview The selection ratio provides information about the value of assessment tools, such as interviews, work samples, and psychometric tests. When the selection ratio is close to one, most applicants will need to be hired in order to fill the available positions. As such knowing that one applicant is likely to perform better than another is of limited value. In contrast when the selection ratio is closer to zero, assessment tools have greater value in indicating which subset of job applicants are likely to perform best. Estimates of the selection ratio can form part of estimates of utility As a topic of economics, utility is used to model worth or value. Its usage has evolved s ...

Recruitment
Recruitment is the overall process of identifying, sourcing, screening, shortlisting, and interviewing candidates for jobs (either permanent or temporary) within an organization. Recruitment also is the processes involved in choosing individuals for unpaid roles. Managers, human resource generalists and recruitment specialists may be tasked with carrying out recruitment, but in some cases public-sector employment, commercial recruitment agencies, or specialist search consultancies are used to undertake parts of the process. Internet-based technologies which support all aspects of recruitment have become widespread, including the use of artificial intelligence (AI). Process * Job analysis for new jobs or substantially changed jobs. It might be undertaken to document the knowledge, skills, abilities and other characteristics (KSAOs) required or sought for the job. From these, the relevant information is captured in a person specification. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interview
An interview is a structured conversation where one participant asks questions, and the other provides answers.Merriam Webster DictionaryInterview Dictionary definition, Retrieved February 16, 2016 In common parlance, the word "interview" refers to a one-on-one conversation between an ''interviewer'' and an ''interviewee''. The interviewer asks questions to which the interviewee responds, usually providing information. That information may be used or provided to other audiences immediately or later. This feature is common to many types of interviews – a job interview or interview with a witness to an event may have no other audience present at the time, but the answers will be later provided to others in the employment or investigative process. An interview may also transfer information in both directions. Interviews usually take place face-to-face and in person but the parties may instead be separated geographically, as in videoconferencing or telephone interviews. I ...

Psychometrics
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales. Practitioners are described as psychometricians, although not all who engage in psychometric research go by this title. Psychometricians usually possess specific qualifications such as degrees or certifications, and most are psychologists with advanced graduate training in psychometrics and measurement theory. I ...

Estimation
Estimation (or estimating) is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.C. Lon Enloe, Elizabeth Garnett, Jonathan Miles, ''Physical Science: What the Technology Professional Needs to Know'' (2000), p. 47. Typically, estimation involves "using the value of a statistic derived from a sample to estimate the value of a corresponding population parameter".Raymond A. Kent, "Estimation", ''Data Construction and Data Analysis for Survey Research'' (2001), p. 157. The sample provides information that can be projected, through various formal or informal processes, to determine a range most likely to describe the missing information. An estimate that turns out to be incorrect will be an overestimate if the estimate exceeds the actual result and an underestimate if the estimate fall ...

Utility
As a topic of economics, utility is used to model worth or value. Its usage has evolved significantly over time. The term was introduced initially as a measure of pleasure or happiness as part of the theory of utilitarianism by moral philosophers such as Jeremy Bentham and John Stuart Mill. The term has been adapted and reapplied within neoclassical economics, which dominates modern economic theory, as a utility function that represents a single consumer's preference ordering over a choice set but is not comparable across consumers. This concept of utility is personal and based on choice rather than on pleasure received, and so is specified more rigorously than the original concept but makes it less useful (and controversial) for ethical decisions. Utility function Consider a set of alternatives among which a person can make a preference ordering. The utility obtained from these alternatives is an unknown function of the utilities obtained from each alternative, not the sum of ...
