Based off of the hit television show NUMB3RS, this lesson has students create box-and-whisker plots for given data, and then determine which (if any) data points are outliers. Students determine outliers through two methods in this lesson: recognizing points that are significantly "far" from the quartiles on the box-and-whisker, and also by observing differences in the correlation of a scatterplot when possible outliers have been removed from the data set. Students practice both of these methods in this calculator-intensive lesson.

Based off of the hit television show NUMB3RS, this lesson introduces students to the odds ratio, a method in statistics for determining if the findings of two groups are statistically significant to each other. Students will find probabilities, odds, and finally the odds ratio of two groups. As an extension, students will explore the logit function.

This set contains statistics questions regarding the normal curve, its distribution, and its applications. The student, using the correct calculation, transitions between observed x-values, standard z-scores, and normal curve areas.

In this activity, students will apply the normal density function, normal cumulative distribution function, and inverse normal cumulative function to analyze a population with a normal distribution.

Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.

This activity is for use as a formative assessment tool after the introduction and overview of parallel and perpendicular slopes.

Students use the TI-89 with CABRI Geometry to discover properties of parallelograms. They will construct a figure and use the definition to discover the figure is a parallelogram.

This activity is designed to assess the comprehension of concepts related to periodic law.

Learn how to graph a piecewise defined function on the TI-89 graphing calculator. Precise keystroke instructions and calculator screenprints are included in this lesson plan and student activity page.

This StudyCard set shows that the product of linear functions (polynomial) is usually quadratic. Students discover the exact product and more traditional methods for multiplying polynomials.

This set of questions pertains to probability: pairs of events, mutually exclusive events, complementary events, expected values, independent events, and conditional probability. Solutions and explanations are included.

Use simulation on the TI-83 graphing calculator to teach students about the distribution of sample proportions, distribution of sample means, the Central Limit Theorem, normal probability plots, and the Law of Large Numbers. Pick and choose topics from within this lengthy activity. Instructions include step-by-step calculator keystrokes as well as calculator screenprints.

In these questions, students use the fundamental counting principle, combinations and permutations to determine the number of possible outcomes and the probability. Solutions and explanations are included.

In this activity, students use simulation to justify the concept of the Law of Large Numbers. They understand that as the sample size increases, the relative frequency of which an event occurs approaches the probability of that event happening. Students investigate the binomial and geometric probability functions, and determine the mean and standard deviation.

Students will generate parabolas using the motion sensor. They will then determine the vertex form of the equation and compare it to the regression equation from the calculator.

Students review the definition of rational numbers as ratios and as terminating and repeating decimals. They also examine the reciprocal property of rational numbers and operations with rational numbers.

The study of properties of right triangles is a major topic in mathematics. In this activity, you will investigate three common right triangle trigonometric ratios. [Requires Adobe Reader.]

In this activity, students recognize the relationship of angles to circles. They study the Inscribed Angle Theorem and its corollaries.
