7th Grade Matix: Statistics, Data Analysis, and Probability

Number Sense | Algebra and Functions | Measurement and Geometry | Statistics, Data Analysis, and Probability

SDP 1.0 Students collect, organize and represent data sets that have one or more variables and identify relationships among variables within a data set by hand and through the use of an electronic spreadsheet program.

SDP 1.1 Know various forms of display for datasets including stem-and-leaf plot, box-and-whisker plot; use the forms to display a single set of data or compare two sets of data.

Exploring Data - curriculum support materials for teachers of introductory statistics. From Boxplots and datasets to linear regression and probability, find everything you could possibly need. Many topics contain worksheets and downloadable files.

Trashketball - Modeling Middle School Mathematics site uses QuickTime video lessons to model best practices. In this game of "trashketball," students take their best shots with their left hand and right hand, then compare data sets. They learn about stem-and-leaf plots and analyze the data to find the mean, median, mode, cluster etc. Includes discussion and reflection.

SDP 1.2 Represent two numerical variables on a scatter plot and informally describe how the data points are distributed and any apparent relationship that exists between the two variables (e.g., between time spent on homework and grade level).

Scatter Plots, Activity A – guided practice and exploration with scatter plots in relating two sets of data.

Scatter Plots - Students collect data about two different characteristics within a population and plot data using virtual manipulatives to investigate whether there is a relationship between two variables.

Correlation – explore correlation coefficients and estimation of line of best fit.

SDP 1.3 Understand the meaning of, and be able to compute, the minimum, the lower quartile, the median, the upper quartile, and the maximum of a data set.

Mean, Median, and Mode video - At the bottom of this page is a catchy tune that your students will enjoy to review the concepts of mode, mean, and median.

The Pizza Palace - Students (in groups of 3) design a pizza and use a calculator to find out its cost. They record the mean, median and mode for the prices of three pizzas and demonstrate positions on a box plot.

Stem & Leaf Plotter - This activity generates a stem and leaf plot from data that the user enters. Users must have data to enter in order to effectively use the applet. This activity would work well in groups of two to four. Includes exploration questions and discussion.

If A Tree Fell In the Woods, Would It Be Part of A Stem-And-Leaf Plot? - Students will learn about stem-and-leaf plots and compare the visual display of these plots with those of bar, line, and pie charts in order to determine when stem-and-leaf plots offer the best option for displaying a data set.
