AP Statistics Syllabus Primary Textbook Yates, Daniel S.; Moore, David S.; Starnes, Daren S. The Practice of Statistics 4th edition. New York, New York: W. H. Freeman and Co., 2003 Course Description: Statistics is the science of data. The purpose of this course is to introduce the students to the major concepts and tools needed for collecting, analyzing, and drawing conclusions from data. This course concentrates on four broad conceptual themes: exploring data, planning a study (collecting data), probability (anticipating patterns in data), and statistical inference based on data. This course is an active learning experience. Students analyze data with calculators and computers. They conduct classroom experiments, carry out individual and group projects, and perform stimulations involving probability concepts. Students are required to write a statistical report reporting their conclusions based on their data. Course Overview AP Statistics at our school is equivalent to a one-semester college course in introductory statistics. To develop effective statistical communication skills, students are required to prepare frequent written and oral analyses of real data. Early in the year, students observe the effects of random phenomena and use Fathom frequently to view the long-term outcomes. Students are taught both elementary probability theory and combinatorial theory, but the emphasis for the probability section is placed on probability modeling. Students use graphical and numerical techniques to study patterns and departures from patterns. They use descriptive statistics to illustrate characteristics of data sets and from observing these characteristics the student makes informed speculations about the relationship of variables. A clear difference between association and causation is developed by many examples encountered with these problems. The students analyze sample surveys and experiments to further clarify the difference between association and causation. Learners hypothesize about a population parameter, create their own surveys and experiments, observe the effects of bias and determine the best inference procedures. Once the population parameter is chosen, and inference model selected, students work using probability modeling to determine if their acquired statistics provide enough evidence to make conclusions about the respected populations. The statistics course will teach students to communicate methods, results, and interpretations using the vocabulary of statistics. Use of Technology Graphing calculators and computers are used throughout the course of the program to assist students in solving problems, interpreting output, visualizing distributions, and observe random behavior. Programs utilized are Fathom statistical software and Microsoft Excel. Students observe Minitab statistical software output and use various applets, ie Normal Distributions, to observe statistical theory in action. The 1 school provides each student with a TI-84 plus for use during the academic year. Students are expected to bring their calculators to all classes and be proficient with their use and graphing capabilities. The students have access to two computer labs with both Excel and Fathom software and TI-Connect. The instructor uses an interactive white board technology, SmartBoard, during lectures, so the students may have access to visual computer output and applets during most lectures. Course Outline I. Exploring Data: Describing patterns and departures from patterns A. Constructing and interpreting graphical displays of the distribution of univariate data 1. Students construct and interpret graphical displays of univariate data using histograms, stem-leaf plots, dotplots, boxplots and ogives. B. Summarizing distributions of univariate data 1. They observe and describe characteristics of the center and spread, clusters and gaps, outliers and unusual features and overall shape. The student will summarize the univariate data distribution using measures of center (mean and median), using measures of spread (range, IQR, standard deviation) and measures of position (z-scores, 5 number summary, and percentiles). They observe the effects of changing units on the above descriptors and discuss the meaning of “resistance”. C. Comparing distributions of univariate data 1. Students use dotplots, same axis histograms, back-to-back stemplots and parallel boxplots to compare center and spread within individual groups and compared groups. They also transcribe comparisons of clusters and gaps, outliers and unusual features and shapes of the individual groups. D. Exploring bivariate data 1. Students analyze patterns in scatterplots using both TI calculators, Excel and Fathom. They examine the distribution of the explanatory and response variables for correlation and linearity and explore the concept of error. Several technology uses are employed to discover the least squares regression line and the effect of outliers and influential points. Students use residual plots to help determine linearity and use logarithmic and power transformations to achieve linearity in nonlinear data sets. E. Exploring categorical data 1. Students use frequency tables, bar charts, segments bar charts and pie charts to help describe qualitative data sets. They use marginal and joint frequencies and conditional relative frequencies to explore the idea of independence and associations. Additionally, students use segmented bar charts and side by side bar charts to compare categorical data sets. 2 II. Sampling and Experimentation: Planning and conducting a study. A. Methods of data collection 1. Students discuss and describe the difference between various data collection methods: census, sample survey, experiments and observational studies. B. Planning and conducting surveys 1. Students plan and conduct their own surveys with an emphasis placed on what question about their population would they like answered and the best survey type to be employed for their study. They discuss the benefits of reducing bias by SRS, but are encouraged to see the positive uses of systematic, stratification, and cluster sampling. C. Planning and conducting experiments 1. Students observe the characteristics of a well-designed and wellconducted experiments and discuss in depth what errors can occur and the devastating results of poorly conducted and analyzed experiments. Students learn the building blocks of experimental design, the importance of complete randomization, and the purpose of varied treatments, control groups, random assignments and replication of the experimental units. Students discuss Hawthorne effect, placebo effect and the effects of blinding. Additionally, they discover the benefits of blocking, and matched pair and the importance of randomization within these methods. D. Generalizability of results and types of conclusions from the above methods 1. Students discuss the importance of cause and effect versus association that can be derived from studies and experiments. An emphasis is put on the fact that one can never be 100% sure and how many pharmaceutical companies now pay the price for incorrect conclusions. III. Anticipating patterns: Exploring random phenomena using probability and simulation. A. Probability 1. Students use Activstats to explore the idea of long run frequency and the Law of Large numbers. We devote several lessons to elementary probability including set theory, probability theory (additional rule, multiplication rule, conditional probability and independence) and combinatorial theory. Following combinations, students examine Bernoulli trials and Poisson distributions. Included in the Bernoulli trials are binomial distributions, geometric distributions and hyper geometric distributions. Accordingly, they determine the mean and 3 variance of probability models (including the Bernoulli and Poisson) and the results of transformations to the random variable that the distribution describes. Students use their TI calculators and random number tables to simulate the behavior of probability models and draw conclusions about random behavior. B. Combining independent random variables 1. Students discuss the effects of independence on random variables and using the “Pythagorean Theorem” of random variables, determine the basis behind adding variance. Students write frequently about combining and finding the difference between independent and dependent random variables. C. The normal distribution 1. Students examine many distributions in this class, but none is more emphasized than the normal distribution. Students collect and examine many data sets and observe the properties of the normal curve. They are taught the use of both their TI calculator and the z-table for predicting areas and values. Students use the normal model for area descriptions. D. Sampling distributions 1. Students examine through tactile manipulatives, Fathom, and Java applets the sampling distribution of sample means and sample proportions. Further exploration using these methods allows the students visually attest to the results of these distributions and the sample size increases, allowing comprehension of the Central Limit Theorem on the basic level. Confirming that two populations are independent, students examine and have discussions about the difference between two independent sample proportions and two independent sample means. Students realize the importance of the student tdistribution in describing data sets with unknown population variances and examine the uses of chi-square distributions. IV. Statistical Inference: Estimating population parameters and testing hypothesis A. Estimation 1. Students determine the criteria of an unbiased estimator for population parameters and how the variability of poor samples affects those results. Through the use of applets, Fathom and calculator activities, students examine the logic of confidence intervals in estimating a population parameter, the meaning of what a confidence interval actually is, describe in context of a given problem what their acquired confidence interval says about their parameter estimate and properties of a confidence interval. Students use probability notation, tables and calculators to define large sample confidence intervals for proportion and mean and for difference between two proportions and two means. Students 4 examine error of the least squares regression line and determine confidence intervals for slopes about said lines using Fathom and TI calculators. B. Tests of Significance 1. Students discourse about the meaning of “significance” and what it means to be statistically significant. They practice writing null and alternative hypothesis, examine the importance of the pvalue as the likelihood of getting a result as extreme as the one acquired. Perform one and two tailed tests and discuss the Power of the test and the likelihood of a Type I and Type II error, what these errors mean in context of the problem and how to reduce said errors while keeping Power strong. Students learn the importance of having the correct conditions before exploring the use of a model with inferential prediction. Students perform a series of inference testing including t-test for means, z-test for means when sigma is known, matched pair t-test for difference of means, t-test for difference of means for independent populations, z-test for proportions, and z-test for difference of proportions. Students additionally discuss the idea of pooling data and post AP exam, explore f-distribution for that purpose. Students perform chi-square tests for goodness of fit for one way tables and homogeneity and independence for two-way tables. Additionally, students test the slope for least square regression lines to determine if the line is statistically suitable for the model. 5 Material Covered by Section I.
