The Bell Curve (Lesson)
Introduces the normal distribution and looks at the bell curve controversy.
This worksheet is for use with the Parametric GraphIt activity (http://www.shodor.org/interactivate/activities/ParametricGraphIt/).
This applet allows the user to experiment with randomly generated data sets at various sample sizes and standard deviations. Then, users can compare the distribution of the experimental data to the expected distribution.
Conic Flyer (Activity)
Manipulate different types of conic section equations on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph. Choose from vertical or horizontal parabola, circle, ellipse, and vertical or horizontal hyperbola.
Students compare multiple independent variables as predictors of one dependent variable. Students explore correlation and lines of best-fit.
InteGreat! (Activity)
InteGreat! allows the user to visually explore the idea of integration through approximating the integral value with partitions. The user controls the number of partitions, the upper and lower limits, and the method used to estimate the integral.
This worksheet is for use with the lesson InteGreat (http://www.shodor.org/interactivate/lessons/InteGreat/).
Looks at how irregular fractals can be generated and how they fit into computer graphics.
This worksheet is for use with the activity Cross Section Flyer (http://www.shodor.org/interactivate/activities/CrossSectionFlyer/).
Polar Coordinates (Activity)
This activity allows the user to explore the polar coordinate system. The applet is similar to GraphIt, but instead allows users to explore the representation of a function in the polar coordinate system.
