## 8th Grade Math Standards - Data Analysis, Statistics, and Probability

To work on Eighth grade data analysis, statistics, and probability standards, click on the standard numbers below to visit pages with internet resources for each of the learning standards.

Checks for Understanding are at the top of this page. Scroll down to find internet resources related to the State Performance Indicators (SPIs).

### Checks for Understanding (Formative/Summative Assessment)

0806.4.1

Probability and Relative Frequency - Solve simple problems involving probability and relative frequency.

0806.4.2 Compare Probabilities - Compare probabilities of two or more events and recognize when certain events are equally likely.
0806.4.3 Dependent and Independent Events - Recognize common misconceptions associated with dependent and independent events.
0806.4.4 Data Representation - Explain the benefits and the limitations of various representations (i.e., bar graphs, line graphs, circle graphs, histograms, stem-and-leaf plots, box plots, scatterplots) of data.
0806.4.5 Types of Plots - Create and interpret box-and-whisker plots and scatterplots.
0806.4.6 Conjectures About a Population - Use observations about differences between two or more samples to make conjectures about the populations from which the samples were taken.
0806.4.7 Best Fit - Estimate lines of best fit to make and test conjectures.
0806.4.8 Statistics in the Media - Consider the source, design, analysis, and display of data to evaluate statistics reported in the media.

### State Performance Indicators

SPI 0806.4.1 Probability - Calculate probabilities of events for simple experiments with equally probable outcomes.
SPI 0806.4.2 Compound Events - Use a variety of methods to compute probabilities for compound events (e.g., multiplication, organized lists, tree diagrams, area models).
SPI 0806.4.3 Generalize a Relationship - Generalize the relationship between two sets of data using scatterplots and lines of best fit.
SPI 0806.4.4 Misrepresentations of Data - Recognize misrepresentations of published data in the media. Data Analysis and Probability - [Grades 6-8] from the National Library of Virtual Manipulatives Internet4classrooms is a collaborative effort by Susan Brooks and Bill Byles.
