This paper summarizes an experiment conducted to examine the counting performance of 7- and 8-year-olds. Analysis of variance was computed on counting errors produced when enumerating a set of squares on a computer screen. The factors included in the analysis were age, gender, array size, error type, proximity, and error form. The primary…

A study investigated the effect of writing in statistics classes on students' interpretation skills (translating the results of data analysis into verbal interpretations that are accessible to non-statisticians). One hundred twenty-two students in three statistics classes received either low, moderate, or high instructional emphasis in…

Describes classroom activities and shows that statistics is a practical tool for solving real problems. Presents a histogram, a stem plot, and a box plot to compare data involving class enrollments. (YP)

In three experiments, the authors investigated whether statistical language influences readers' interpretations of research results. Although the authors argue that "significant" language changes should not be mandated for quantitative research studies in scientific journals, if such changes are mandated, then use of the term "statistical" is…

Presents activities having to do with data generation, organization, interpretation, representation, drawing conclusions, and making predictions on the basis of data which students have collected. (ASK)

Discusses the use or misuse of statistics or probability in society. Presented are examples from opinion polling, sports, the 1970 draft lottery, and the law. Lists 18 references. (YP)

To study how the organization of information affects the way that information is interpreted, a total of 404 undergraduates in two studies (151 and 253 students, respectively) solved statistical reasoning problems based on data presented in a variety of types of graphs and tables. When assessing relative probabilities, students were equally…

Presents an activity to analyze the data from the Challenger explosion to help students understand the critical role of statistics in decision making and the importance of considering all available data. (MKR)

Demonstrates a statistically valid method allowing students to explore randomization. Described are two examples: counting techniques for a small set of data and simulation for a large sample. (YP)

Assesses the progress made in computational stylistics over the past 25 years. Discusses theoretical notions of style. Describes certain trends that emerge from relevant articles in conference proceedings and academic journals. Concludes there has been progress in the accumulation of data, the creation of databases and archives, and construction…

Statistical literacy is defined as "the ability to read and interpret data: the ability to use statistics as evidence in arguments. Statistical literacy is a competency: the ability to think critically about statistics" (Schield, p. 2). When a definition of statistical literacy is considered it can be seen that all students can manage a…

Data collection and analysis are frequently neglected by school leaders over the course of the decision-making process. All schools gather large amounts of information about students and teachers, but most data are used to satisfy administrative requirements rather than evaluate school improvement in a systematic fashion. Apprehension regarding…

Describes two QuickBASIC programs that provide students direct experience with interpreting correlation scatter-plots. Maintains that the programs can be used in classroom exercises to highlight factors that influence the size of a Pearson correlation coefficient. (CFR)

Describes a QuickBASIC program for demonstrating the differences between main effects and interactions in factorial designs. The program can be used in conjunction with a traditional lecture to improve student understanding and develop skills in recognizing main effects and interactions from graphic displays. (CFR)

Many social workers are anxious about the use of evaluation techniques and are particularly reticent about using statistical research. Strategies for understanding the steps involved in integrating practice and evaluation in a school social work setting, an appreciation for the need of evaluation, and knowledge of various resources on conducting…
