6. Bivariate Data - Examining Relationships (S2)
Students plot and interpret bivariate data by constructing scatterplots, recognizing linear and nonlinear patterns, and interpreting correlation coefficients; they fit and interpret regression models, using technology as appropriate.
High School
- S2.1 Scatterplots and Correlation
- Data Analysis and Statistics Lessons - This site is an introduction to descriptive statistics and focuses on the fact that we use statistics in our everyday life. The site begins with an introduction to the teacher. The link at the bottom of the page will send you to student activities on Mode, Median, Mean, Central Tendency,Variation, Range, Variance and Standard Deviation.
- Simple Plot - This site contains information, an interactive coordinate plane for students and lesson plan for teacher. The activity helps students associate ordered pairs with their location on a coordinate plane.
- S2.2 Linear Regression
- El Nino or El No-no - Inference and Prediction (III.3.HS.3&4) - Student interactive site where the students collect data (Water temperatures from ocean buoys.) and present it using different statistical methods. They will then predict what the future weather patterns will be from their collected data. This is a Webquest site
- Finite Mathematics - Outstanding - This site provides students with on-line tutorials to aid in solving systems of two linear equations in two unknowns, using matrices to solve systems of equations, and applications of systems of linear equations.
- Global Warming Statistics - Inference and Prediction (III.3.HS.4) - This site is a good resource for teachers and contains an activity for the students to collect data on the Internet about changing climates. The students then analyze the data with statistics as well as plot graphs and extrapolate.
- Put the Heart into Mathematics - Inference and Prediction (III.3.HS.1,2,3,4&5) - Outstanding - This NCTM (Illuminations) activity is geared for students in grades 9-12. This unit contains four different teacher lesson plans with reproducible student worksheets, and interactive graphing and data collection capabilities. The lessons provided explore cardiac output by measuring the amount of blood being pumped by an experimental heart. Students will explore rates of change and accumulation in the context of cardiac output and accumulation using hands on experimentation, data collection, "pencil and paper" activities, etc,.
- Shedding Light on the Subject: Function Models of Light Decay - Inference and Prediction (III.3.HS.3,4&5) - Presented by NCTM (Illuminations), this website provides the teacher with a four lesson unit on the decay of light as an exponential model. Teachers will appreciate the printer friendly lesson plans accompanied by student objectives, worksheets, and references. The site includes an interactive grapher and downloadable movie clips (quick time required) for students.
- What Percentage of your Class is Right or Left Handed? - Inference and Prediction (III.3.HS.4&5) - Cythia Lanius provides this lesson for high school students to determine the percentage of students that are right or left handed in a classroom. Students perform experiments, collect data, graph the data, and analyze their findings. Worksheets, spreadsheets and teacher notes are available.
