Data Analysis and Probability Standard

Instructional programs from pre-K through grade 12 should enable all students to --

Standard Component Interactivate Lessons	Grades 6-8 Expectations
formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them; Probability and Sports Statistics and Shopping Stem-and-Leaf Plots Histograms and Bar Graphs Box Plots The Bell Curve	formulate questions, design studies, and collect data about a characteristic shared by two populations or different characteristics within one population; select, create, and use appropriate graphical representations of data, including histograms, box plots, and scatter plots.
select and use appropriate statistical methods to analyze data; Expected Value Unexpected Answers Statistics and Shopping Mean, Median and Mode Stem-and-Leaf Plots Histograms and Bar Graphs Box Plots The Bell Curve	find, use, and interpret measures of center and spread, including mean and interquartile range; discuss and understand the correspondence between data sets and their graphical representations, especially histograms, stem-and-leaf plots, box plots, and scatter plots.
develop and evaluate inferences and predictions that are based on data; Probability and Sports Expected Value Statistics and Shopping Stem-and-Leaf Plots Histograms and Bar Graphs Box Plots The Bell Curve	use observations about differences between two or more samples to make conjectures about populations from which the samples were taken; make conjectures about possible relationships between two characteristics of a sample on the basis of scatter plots of the data and approximate lines of fit; use conjectures to formulate new questions and plan new studies to answer them.
understand and apply basic concepts of probability. Probability and Sports Ideas that Lead to Probability Introduction to the Concept of Probability Probability and Geometry Conditional Probability and Probability of Simultaneous Events Replacement and Probability From Probability to Combinatorics and Number Theory Expected Value	understand and use appropriate terminology to describe complementary and mutually exclusive events; use proportionality and a basic understanding of probability to make and test conjectures about the results of experiments and simulations; compute probabilities for simple compound events, using such methods as organized lists, tree diagrams, and area models.
