The statistical concept of sampling is often given little direct attention, typically reduced to the mantra "take a random sample". This low resource and adaptable activity demonstrates sampling and explores issues that arise due to biased sampling.

In the era of Big Data, because of diminishing cost of data collection and storage, a large number of statistical tests may even possibly be conducted all together by a high school student to seek for some "exciting" new scientific findings. In this article, we propose an interesting approach to introduce students to some important…

In the criminal justice system, defendants accused of a crime are presumed innocent until proven guilty. Statistical inference in any context is built on an analogous principle: The null hypothesis--often a hypothesis of "no difference" or "no effect"--is presumed true unless there is sufficient evidence against it. In this…

The relevance of the study is due to the importance of psychological and pedagogical support for students in university that would prevent difficulties in learning activities and increase adaptive capacity through the development of relevant personal traits. Therefore, this article is aimed at solving the problem of arranging psychological and…

An exciting event had occurred for the grade 3 classes at Woodlands State School. A new play space designated for the older grades had now been opened to the third graders. In sharing their excitement over this "real treat, real privilege," the teachers invited the children to find out more about playgrounds and, in particular, their new…

This article describes a fun activity that can be used to help students make links between statistical analyses and their real-world implications. Although an illustrative example is provided using analysis of variance, the activity may be adapted for use with other statistical techniques.

Discusses experiences in elementary statistics that involve describing data by measures of central tendency and dispersion and that are appropriate for students in secondary schools. Includes background information, instructional strategies, procedures, and a ready-to-duplicate student worksheet. (JN)

This book discusses two major approaches to social science research: quantitative research, which involves converting observations to numbers and analyzing them statistically; and qualitative research, which looks at participants' opinions, behaviors, and experiences from their own points of view and in a more subjective way. In the book,…

This instructor guide, which was developed for use in a manufacturing firm's advanced technical preparation program, contains the materials required to present a learning module that is designed to prepare trainees for the program's statistical process control module by improving their basic math skills in working with line graphs and teaching…

Looks at the effect of student-written test questions on student test performance. Students either wrote essay or multiple-choice questions, or did not write questions. Student items were not used on the test. Results indicate that question-writing is an effective studying technique. (Author/LS)

Describes the statistical test of chi-square analysis. Explains how this test can be used in biology instruction. Examples from blood typing are used. (PR)

Presents the origin and mathematics of Hubble's Law of the expanding universe. Discusses limitations to this law and the related concepts of standard candles, elliptical galaxies, and streaming motions, which are conspicuous deviations from the law. The third of three models proposed as explanations for streaming motions is designated: The Great…

Observes that students in introductory and intermediate economics courses often have difficulty understanding concepts of trade and budget deficits. Presents a graphical technique to be used as a framework for teaching these concepts in the classroom. Claims that this technique is effective in other comparative statistics exercises. (NL)

Discusses how nonparametric statistical procedures can be applied to the scoring of cross-country running races. Asserts that this type of example in statistics is appropriate for the upper-secondary school and lower-division college levels. (MDH)
