TITLE : Unit 11: Linear, Quadratic, and Exponential Data Models SUGGESTED DURATION : 5 days

Unit Overview

This unit bundles student expectations that address analyzing sets of data using technology to determine if the data is best represented using linear, quadratic, or exponential models and applying the selected models to make predictions and critical judgments in terms of the data. Concepts are incorporated into both mathematical and real-world problem situations. According to the Texas Education Agency, mathematical process standards including application, tools and techniques, communication, representations, relationships, and justifications should be integrated (when applicable) with content knowledge and skills so that students are prepared to use mathematics in everyday life, society, and the workplace.

Prior to this unit, in Algebra I Units 03, 08, and 09, students were introduced to linear, quadratic, and exponential functions. In Algebra II Units 05 and 09, students analyzed quadratic and exponential functions. Linear functions were interspersed throughout Algebra II.

During this unit, students analyze and compare linear, quadratic, and exponential data sets using graphs, tables, verbal descriptions, and technology to determine which function can be selected to best model the data. Students use regression methods available through technology to write the appropriate regression function (linear, quadratic, or exponential) to model the data. Students apply the regression model to predict and make decisions and critical judgments in terms of the data.

After this unit, in Algebra II Units 12 and 13, students will review and continue to apply linear, quadratic, and exponential functions. In subsequent mathematics courses, students will also continue to apply these concepts when linear, quadratic, and exponential functions and equations arise in problem situations.

In Algebra II, analysis of sets of data to select an appropriate regression equation and application of that regression equation to make predictions and critical judgments are identified as STAAR Readiness Standard 2A.8C and STAAR Supporting Standards 2A.8A and 2A.8B. These standards are subsumed under STAAR Reporting Category 2: Describing and Graphing Functions and Their Inverses. This unit is supporting the development of Texas College and Career Readiness Standards (TxCCRS): I. Numeric Reasoning B1; II. Algebraic Reasoning A1, B1, C1, D1, D2; III. Geometric Reasoning B2, C1; VII. Functions A2, B1, B2; VIII. Problem Solving and Reasoning; IX. Communication and Representation; X. Connections.

According to the National Council of Teachers of Mathematics (2011), Developing Essential Understanding of Functions, Grades 9-12, understanding of the function concept is essential to describing and analyzing quantities which vary with respect to one another. According to research from the National Council of Teachers of Mathematics (2000), Principles And Standards For School Mathematics, high school algebra should provide students with insights into mathematical abstraction and structure. High school students’ algebra experience should enable them to create and use tabular, symbolic, graphical, and verbal representations and to analyze and understand patterns, relations, and functions with a higher degree of sophistication. Students should develop an understanding of the algebraic properties that govern manipulation of symbols in expressions, equations, and inequalities.

MISCONCEPTIONS / UNDERDEVELOPED CONCEPTS

Misconceptions:

  • Some students may think a scatterplot is linear because the points appear to be almost a line, rather than doing a regression analysis and comparing correlation coefficients. Parts of a quadratic relationship and parts of an exponential relationship may appear linear without in-depth analysis.
  • Some students may fail to put data in sequential order before checking first and second differences and common ratios.
  • Some students may check on first and second differences and fail to check common ratios when analyzing sequential data.
  • Some students may not put values in the correct order when calculating first and second differences (not y1y2, but y2y1).
  • Some students may not put values in the correct order when calculating the common ratio (not , but ).

Unit Vocabulary

  • Regression equation – line of best fit representing a set of bivariate data
  • Correlation coefficient (r-value) – numeric value that assesses the strength of the linear relationship between two quantitative variables in a set of bivariate data
  • Coefficient of determination (r2-value) – representation of the percent of data closest to the regression line and used to measure how well the regression line can be used as a prediction model

 

Related Vocabulary:

For Kindergarten and Grade 1, certain of these student expectations do not apply until the student has reached the stage of generating original written text using a standard writing system. The student is expected to:
ELPS.c.5A learn relationships between sounds and letters of the English language to represent sounds when writing in English
ELPS.c.5B write using newly acquired basic vocabulary and content-based grade-level vocabulary
ELPS.c.5C spell familiar English words with increasing accuracy, and employ English spelling patterns and rules with increasing accuracy as more English is acquired
ELPS.c.5D edit writing for standard grammar and usage, including subject-verb agreement, pronoun agreement, and appropriate verb tenses commensurate with grade-level expectations as more English is acquired
ELPS.c.5E employ increasingly complex grammatical structures in content area writing commensurate with grade-level expectations, such as:
ELPS.c.5F write using a variety of grade-appropriate sentence lengths, patterns, and connecting words to combine phrases, clauses, and sentences in increasingly accurate ways as more English is acquired
ELPS.c.5G narrate, describe, and explain with increasing specificity and detail to fulfill content area writing needs as more English is acquired.
