About This Chapter
Bivariate Data - Chapter Summary
Help your students fully comprehend bivariate data with this chapter's video and text lessons. Each lesson is presented by an expert instructor and can be viewed in any sequence the student desires. After exploring definitions, equations and formulas associated with bivariate data in this chapter, students will be able to:
- Define and describe bivariate data
- Demonstrate the process of creating and interpreting scatterplots
- Show how to calculate and analyze a trend line in math
- Find the regression line of a set of data using a graphing calculator and ruler
- Showcase an understanding of mean absolute deviation
Lessons feature self-assessment quizzes students can use to assess their knowledge of bivariate data. A chapter exam is also available to reinforce concepts explored in the lessons. Students can access the lessons any time, day or night, from a smartphone, computer or tablet. Any questions they have about lesson topics can be submitted to our experts.
1. What is Bivariate Data? - Definition & Examples
In this lesson, you will be learning about the definition and uses of bivariate data. We will also compare and contrast the characteristics of univariate data and bivariate data.
2. Creating & Interpreting Scatterplots: Process & Examples
Scatterplots are a great visual representation of two sets of data. In this lesson, you will learn how to interpret bivariate data to create scatterplots and understand the relationship between the two variables.
3. What is a Trend Line in Math? - Definition, Equation & Analysis
Learn about trend lines, including what they are, how to calculate them, and how to interpret them when they are used in a graph. You will see the concepts unfold in a series of examples that will prepare you for solving a variety of practice problems.
4. Simple Linear Regression: Definition, Formula & Examples
Simple linear regression is a great way to make observations and interpret data. In this lesson, you will learn to find the regression line of a set of data using a ruler and a graphing calculator.
5. What is Mean Absolute Deviation? - Definition & Examples
In this lesson, we will first learn how to use the mean absolute deviation to find not only the average of a set of numbers but the average distance each number is from the average number. Then, we will show a step-by-step, real-world problem, to practice your skills.
