### Chapter 1--Data Exploration

 Essential Question:  How can we model and analyze data to understand real-life situations? Unit Rationale:  Exploring data offers many opportunities to use algebra and see its applications. As a result of this unit, students will be able to: Ø  Make and use a scatter plot to evaluate the relationship between two variables Ø  Draw and justify conclusions about a data set, based on graphs Vocabulary: ·         Accuracy ·         Coordinate Plane ·         Coordinates ·         Measure of Center ·         Measure of Central Tendency ·         Ordered Pair ·         Origin ·         Precision ·         Quadrant ·         Quartile ·         Scatter Plot ·         Variable ·         Inter Quartile Range(IQR)   Standards: Standards will be assessed on both the state and classroom levels, however, standards with an asterisk (*) in the code will count for graduation requirements.  Focus Standards: *A1.6.A Use and evaluate the accuracy of summary statistics to describe and compare data sets Supporting Standards: *A1.2.B Recognize the multiple use of variables, determine all possible values of variables that satisfy prescribed conditions, and evaluate algebraic expressions that involve variables. *A1.6.B Make valid inferences and draw conclusions based on data. Reasoning, Problem Solving, and Communication Standards: A1.8.E Read and interpret diagrams, graphs, and text containing the symbols, language and conventions of mathematics.
