Three experiments which use probabilities to approximate pi are described. (JT)

This biography of the mathematician Girolamo Cardons (1500-1576) sketches his life and discusses his mathematical works, which were controversial at the time. (SD)

Vector sum of a white noise in an unknown hyperspace and an Ornstein-Uhlenbeck process in an unknown line is observed through sharp linear test functions over a finite time span. Parameters associated with white noise are determinable and index measure-equivalence classes in relevant sample space. Intraclass relative density provides a basis for…

Because previous studies had suggestd that Down Syndrome subjects did not respond to changes in directional probability within a complex motor task as did other retarded subjects, 14 Down Syndrome 18-year-olds were given training relative to the directional probability component of the task. Performance was improved but primarily in terms of…

Examined utility of probability statistics to determine optimal symptoms for making differential diagnosis among childhood attention deficit and conduct disorders. Assessed positive and negative predictive power (symptom presence or absence) in psychiatric interviews of 76 clinic-referred boys. Some symptoms proved optimal as inclusion criteria,…

The probability of selecting two matching socks is discussed. (MNS)

Research on what elementary school students know about probability prior to instruction and what they can learn about probability is concisely reviewed. Many references are included. (MNS)

Introduces a new model of viewing documents based on citing-cited relationship between them. Using Bayes' decision theory, it is shown how source document may be indexed and weighted by relevant cited document features, corresponding to one pass relevance feedback Model 1 (probabilistic indexing) or Model 2 (probabilistic retrieval). (24…

A probablistic approach to classification and diagnosis of erroneous rules of operations that result from misconceptions ("bugs") in a procedural domain of arithmetic is introcuced. Variability of response errors is explicitly treated through item response theory. As a concrete example, a signed-number subtraction dataset is analyzed.…

Two specific cases involving Pascal's Problem of the Points are discussed, followed by a solution in the general case. (MNS)

How probabilities change when playing the game of craps with dice having 8, 12, or 20 faces is discussed. Five challenge questions are also included. (MNS)

Relationships between both the elements and the overall characteristics of Pascal's triangle are explored. (DT)

Many research-related classes in social sciences present probability as a unified approach based upon mathematical axioms, but neglect the diversity of various probability theories and their associated philosophical assumptions. Although currently the dominant statistical and probabilistic approach is the Fisherian tradition, the use of Fisherian…

Differences in the probability of graduating were studied for freshmen and transfer students at a metropolitan university. The study was based on students who arrived at Boise State University for the fall 1989 term (n=2,459). Of this group, 1,692 were new freshmen, and 767 were new transfers. The two groups were similar in gender and ethnicity.…

J. Barnette and J. McLean (1996) proposed a method of controlling Type I error in pairwise multiple comparisons after a significant omnibus F test. This procedure, called Alpha-Max, is based on a sequential cumulative probability accounting procedure in line with Bonferroni inequality. A missing element in the discussion of Alpha-Max was the…
