Most K-12 evaluations are designed to make inferences about how a program implemented at the classroom or school level affects student learning outcomes and such inferences inherently involve hierarchical data structure. One methodological challenge for evaluators is linking program implementation factors typically measured at the classroom or…

The Behrens-Fisher problem arises when one seeks to make inferences about the means of two normal populations without assuming the variances are equal. This paper presents a review of fundamental concepts and applications used to address the Behrens-Fisher problem under fiducial, Bayesian, and frequentist approaches. Methods of approximations to…

This discussion on the interpretation of language and the role of inference argues that language is a tool in the sense that it provides the basic operators and rules of operation for speech just as arithmetic does for calculation. It is suggested that because language is a tool that is restricted in its expressive potential by the linguistic…

In rebuttal to a critique of the authors' examination of prevalence rate variability for special education categories, it is claimed that a consideration of the nature of prevalence rate data, the correct use of inferential statistics, and the coefficient of variation itself, suggest the objections are not justified. (Author/DB)

Four experiments investigated the role of geometric path type in infants' ability to make spatial inferences about the location of a hidden object after the infants had been moved. In all but the fourth experiment, infants were able to retrieve the objects unless objects were located behind the infants. (SKC)

To use the concept of probability and uncertainty estimation is a common practice in daily life. To assist students in learning the fundamentals of probability and statistics, not through the usual class and note taking, a group-learning and practical "statistical system" was designed. By connecting with the main statistical center, students not…

In educational assessment, educators observe what students say, do, or make in a few particular circumstances and attempt to infer what they know, can do, or have accomplished more generally. A web of inference connects the two. Some connections depend on theories and experience concerning the targeted knowledge in the domain, how it is acquired,…

Discusses two readings of English plural noun phrases, the collective and distributive, and argues against postulating a hidden operator that would handle the ambiguity. The article postulates principles of combination, giving truth conditions for a sentence with an "n"-place predicate and demonstrative noun phrases as arguments,…

Two studies explored the following two issues important in understanding the development of knowledge-based inferencing: (1) how children of different ages use a circumscribed and available knowledge base to make two types of inferences important for comprehension; and (2) how the accessibility of an available knowledge base is related to…

Investigates conditions that enable viewers to predict future events while viewing a movie. Hypothesizes that predictions about future events can be supported by visual, auditory, and discursive information. Interprets data from two experiments in terms of pragmatic and causal factors in comprehension. (PA)

Presents an overview of a wide range of measurement models currently available to the analyst who needs to make accurate and valid inferences about respondents and stimuli from data. Reviews models with and without predictor variables or observed and latent predictors, as well as parametric and nonparametric models, and models for order-restricted…

Discusses information inference from a psychologistic stance and proposes an information inference mechanism that makes inferences via computations of information flow through an approximation of a conceptual space. Highlights include cognitive economics of information processing; context sensitivity; and query models for information retrieval.…

Whether 10- to 14-year olds infer implied instruments when reading isolated instrument-implicit sentences as well as they do when instructed to generate such instruments was studied with 177 subjects in 2 experiments. Results indicate that spontaneous instrumental inference is less certain than previously suggested. (SLD)

Eleven experiments involving over 200 undergraduate students investigated how categorization of examples influences feature prediction for new examples. Results suggest that category-based prediction generally relies on a single category rather than multiple categories when there is a clear target category. (SLD)

Of 171 undergraduates, 90 viewed a videotape of a "friendly" recruiter and 81 an "unfriendly" recruiter. The former group made significantly more positive inferences regarding the recruiter's organization than did those watching the "unfriendly" tape. These inferences affected their attraction to the job. (SK)
