#### A Data and Statistics Example

This is an introduction to the TI-Nspire Data and Statistics feature. Real data from Subway is used to find the mean, create a histogram and box-and-whisker plots, and find a regression equation. Concepts:
Central tendencies spread of data, histogram, box and whisker plots, and regression equation.

#### A Piece of Pi: An Investigation into Geometric Probability and Pi

Have you ever noticed in how many places π turns up? Students will take part in a Buffon's Needle experiment and see how close they can get to 3.14.

To set up the lesson, there will be a brief historical tour of Pi as well as a clip from NUMB3RS, SEASON 2, Judgment Call. Next, the students will do an experiment and then transfer the data collected to the TI-nSpire where it will be analyzed and interpreted. Last, they will get to explore the problem using a simulated version.

#### An Approximation to the Binomial Distribution

Students will investigate the binomial distribution for a small sample size of 10 with several different values for the probability of a success. Then students will graph a normal density curve along with the binomial distribution to roughly judge how accurately that model fits. Finally, students will discover that the larger the sample size, the less important the probability being close to 0.5 becomes. So, the normal distribution is a reasonable approximation to the binomial distribution.

#### Analyzing the 2008 Steelers' Super Bowl Year

Use the TOUCHPAD Nspire to explore using:
the List & Spreadsheet Page to capture data previously entered as well as insert a column with new data;
the Data & Statistics Page to create and interprete graphs of Dot Plots, Box Plots, and scatterplots.

The learner will also analyze the data using the five number summary, measures of central tendencies, determine the LSRL and use graphs of the residuals and the square of the residuals to verify appropriateness of the y=mx+b regression model.

#### Application of Power

Students use the concept of power to explore how the probability of rejecting the null hypothesis, when it is false, plays a role in a real-world scenario.

#### Application of Sampling Distributions

In this activity, students examine samples from a normal population and observing the distribution of the means of those samples. Then they will observe how the sampling distribution changes as the sample size changes. Students will apply what they have learned to a real-world situation.

#### Are They Truly Random?

Students will develop lists of random numbers generated by the TI-Nspire handheld. They will explore their set of numbers and engage in a discussion of whether the random number generator is truly generating numbers at random.

In addition, students will look at statistical models of their numbers and discuss whether "patterns" they see in the set of random numbers are possible if the numbers are truly random.

#### Areas In Intervals

Students use several methods to determine the probability of a given normally distributed value being in a given interval. First, they use the Integral tool to find areas under the curve and to the left of given values. Students continue the activity to find probabilities for which the corresponding area is greater than a given value, and then they conclude the activity by finding areas between z scores.

#### Assessing Normality

In this activity, students will learn four characteristics of a normal curve: the distribution is symmetric and mound-shaped; the mean and median are approximately equal; the distribution meets the 68-95.5-99.7 rule; and the normal probability plot is linear. They will use these to determine if a data set it normal.

#### Binomial Distribution and Gender Biased Jury Selection

A high profile criminal case in our area gave me the idea of creating a binomial distribution using jury selection based on a selection by gender. Many cases could possibly be determined by the selection of men or women.

#### Binomial Experiments

Students use the multiplication rule for independent events to find the probability of the first success in the nth trial. Students use their results to derive and test a general formula. Then, students expand on this foundation to derive and test a rule for the probability of x successes in n trials.
