Mathematics, Standard E: Statistics and Probability
Performance Standards - Grade 8
By the end of grade eight, students will:
E.8.1 Work with data in the context of real-world situations by:
- formulating questions that lead to data collection and analysis
- designing and conducting a statistical investigation
- using technology to generate displays, summary statistics*,
and presentations
E.8.2 Organize and display data from statistical investigations
using:
- appropriate tables, graphs, and/or charts (e.g., circle, bar
or line for multiple sets of data)
- appropriate plots (e.g., line*, stem-and-leaf*, box*, scatter*)
E.8.3 Extract, interpret, and analyze information from organized
and displayed data by using:
- frequency and distribution, including mode* and range*
- central tendencies* of data (mean* and median*)
- indicators of dispersion (e.g., outliers*)
E.8.4 Use the results of data analysis to:
- make predictions
- develop convincing arguments
- draw conclusions
E.8.5 Compare several sets of data to generate, test, and, as
the data dictate, confirm or deny hypotheses
E.8.6 Evaluate presentations and statistical analyses from a variety
of sources for:
- credibility of the source
- techniques of collection, organization, and presentation of
data
- missing or incorrect data
- inferences
- possible sources of bias
E.8.7 Determine the likelihood of occurrence of simple events
by:
- using a variety of strategies to identify possible outcomes
(e.g., lists, tables, tree diagrams*)
- conducting an experiment
- designing and conducting simulations*
- applying theoretical notions of probability (e.g., that four
equally likely events have a 25% chance of happening)
