7th Grade
Probability and Statistics
7.17 The student, given a problem situation, will collect, analyze, display, and interpret data, using a variety of graphical methods, including frequency distributions; line plots; histograms; stem-and-leaf plots; box-and-whisker plots; and scattergrams.
Lessons (9)
Students discover algorithms as they sort shapes into Venn diagrams. Then students compare the efficiency of their algorithms using box plots.
Introduces students to quartiles and box plots.
Introduces students to plotting points on the Cartesian coordinate system -- an alternative to "Graphing and the Coordinate Plane."
Students learn basic ideas about graphing points on the coordinate plane.
Demonstrates the connections between formulas and graphs.
Introduction and fine points of using bar graphs and histograms.
Introduces the basic ideas needed for understanding linear functions.
Introduces students to stem-and-leaf plots and calculating the mean, median, and mode from the plots.
Students learn about the difference between univariate and bivariate data and understand how to choose the best graph to display the data.
Activities (2)
Enter a set of data points, then derive a function to fit those points. Manipulate the function on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph.
View stem-and-leaf plots of your own data, and then practice finding means, medians and modes. Stem and Leaf Plotter is one of the Interactivate assessment explorers.
