Box-and-whisker plots (which give rapid visualization of batches of data) can be effectively used to present diverse collections of data used in traditional first-year chemistry courses. Construction of box-and-whisker plots and their use with bond energy data and data on heats of formation and solution are discussed. (JN)

It is not conceivable that in a mixture or compound a component may exist in a negative ratio. Traditionally, therefore, a negative value could not be plotted on triangular coordinates. However, negative values are explicitly allowed, and the results extend the use of triangular coordinates as shown in this article. (JN)

Discusses various software packages which help science and mathematics students make sense out of data (formulating hypotheses, interpreting graphs, analyzing possibilities, and collecting data with real-time graphing). Includes a list of commercially available programs for the areas, with program name, publisher, grade level(s), price, and…

Describes a laboratory exercise requiring students to separate a selected number of organisms into groups of increasing similarity and to relate these groups directly to the kingdom-species system of classification. (Author/MA)

Presented is a three-hour instrumental analysis experiment which allows study of software data-handling methods. These methods include sampling, boxcar averaging, smoothing, ensemble averaging, and digital filtering. Use of the program should provide students with a better idea of advantages and disadvantages of using such software data-handling…

Describes a menu-driven, data plotting program which runs on any Apple II plus, IIE, or IIC microcomputer. The program does a least-squares analysis of the data and gives the user the option of fitting the line through the data points. The complete Applesoft program listing is included. (JN)

Presents equations and techniques for calculating and interpreting many of the spectroscopically important parameters associated with the ground and second excited states of the iodine molecule. (Author/CS)

Instructional strategies used in teaching oceanographic data collection techniques are discussed. These include having students examine actual data, plan and organize a research cruise on a specific budget, and analyze incomplete data sets. Rationale for using these strategies is included. (JN)

Identifies and explains some of the crucial elements of team research and data analysis, points out common pitfalls, and makes some helpful suggestions. Sections include general recommendations and communicating in statistical language. (ZWH)

Describes how the statistical technique of meta-analysis can be used to help resolve conflicting studies in social sciences. (ZWH)

Describes two exercises which use data of sporting events (running) in conjunction with biological factors as exercises in interpreting data. (BR)

Describes and compares three analytical methods of interpreting constant acceleration data from a stroboscopic picture or spark record. (CP)

Uses a printed sheet of paper to represent a plant population in a given area. Quadrat sampling is simulated by dropping a square coverslip on the sheet and recording the symbols under the coverslip. Line-transect method is simulated by having a student randomly adjust the sheet under a string. (GS)

Presents a laboratory problem in metamorphic petrology designed to simulate a research experience. The problem deals with data on scales ranging from a geologic map to hand specimens to thin sections. Student analysis includes identifying metamorphic index minerals, locating their isograds on the map, and determining the folding sequence. (BC)
