Directed acyclic graphs (DAGs) are now a popular tool to inform causal inferences. We discuss how DAGs can also be used to encode theoretical assumptions about nonprobability samples and survey nonresponse and to determine whether population quantities including conditional distributions and regressions can be identified. We describe sources of…

Teaching students to collect data to answer questions is an important life skill that will serve them well throughout their adult lives. The purpose of this manuscript is to describe the implementation of an action research project in a fifth grade resource classroom. Students with mild disabilities were taught how to conduct surveys using three…

Discusses trade-off analysis, a data collection method with conjoint measurement technique in which respondents rank order a matrix of pairs of levels of specific attributes, and gives examples for use in determining library users' perceptions of relative utility of completeness of information versus cost of a search. Twelve sources are cited.…

Presents activities using the theme of collecting and interpreting data from the students' own classroom. Stresses communication among students and between students and the teacher. Includes reproducible student worksheets. (MKR)

Suggests a classroom activity for teaching psychology students about group norms. Calls upon students to conduct peer surveys about a particular behavior and then to represent approval or disapproval of the behavior graphically.

This survey of 510 special education teachers found that most teachers collect, record, and use data on student performance to determine instructional effectiveness, appropriate time to move students to the next skill, and which objectives have been met. Only one-third of teachers used graphs for displaying and interpreting data. (Author/JDD)

Presents an analysis of errors in a 400-page corpus of German essays by American college students in second-year language courses showing that syntax is the most problematic area, followed by morphology. This study indicates that 80% of student errors are not of semantic origin and are potentially recognizable by a syntactic parser. (six…

Provides 5 activities for levels K-2, 3-4, 5-6, 7-8, and for the family that incorporate data collection and interpretation in the decision-making process. Activities investigate taste preference, voter preference, meal preference at the school open house, three close presidential elections, and questions about the years and dates of presidential…

Describes four activities for grade levels K-3, 4-5, and 6-8 and for the family that explore statistical concepts using a manipulative familiar to students-SKITTLES candies. Concepts explored include frequency graphs, data collection and analysis, probability, measures of central tendency, averaging, and correlation coefficients. Includes…
