 Teacher resources and professional development across the curriculum

Teacher professional development and classroom resources across the curriculum                   In previous sessions, you provided answers to statistical problems by collecting and analyzing data on one variable. This kind of data analysis is known as univariate analysis. It is designed to draw out potential patterns in the variation in order to provide better answers to statistical questions. In your exploration of univariate analysis, you investigated several approaches to organizing data in graphs and tables, and you explored various numerical summary measures for describing characteristics of a distribution.  Part A:

Scatter Plots  Part B:

Contingency Tables  Part C:

Modeling Linear Relationships  Part D:

Fitting Lines to Data  Homework

 In this session, you will study statistical problems by collecting and analyzing data on two variables. This kind of data analysis, known as bivariate analysis, explores the concept of association between two variables. Association is based on how two variables simultaneously change together -- the notion of co-variation. The goal of this lesson is to understand the concepts of association and co-variation between two quantitative variables. In your investigation, you will do the following: • Graph bivariate data in a scatter plot • Divide the points in a scatter plot into four quadrants • Summarize bivariate data in a contingency table • Model linear relationships • Explore the least squares line   Throughout the session you will be prompted to view short video segments. In addition to these excerpts, you may choose to watch the full-length video of this session.
