1 Pierce College at Joint Base Lewis-McChord Course Syllabus Course dates: 11 July, September, 2017 COURSE TITLE: Introduction to Statistics ABBREVIATION: Math& 146 CREDIT HOURS: 5 INSTRUCTIONAL HOURS: 50 INSTRUCTOR: Dr. Harold Nelson INSTRUCTOR INTRODUCTION: I received my bachelors degree in mathematics from Notre Dame in 1965, my masters in mathematics from the University of Kentucky in 1967 and my PhD in Economics from the University of California, San Diego in I have been teaching for Pierce College since I was employed full time as an economist/statistician by the State of Washington for over 25 years. I have taught classes in statistics at least 100 times. COMMUNICATIONS: All course communications will be through the Canvas course inbox. PREREQUISITE: MATH 096 or MATH 098 or equivalent with a grade of at least 2.0 or satisfactory placement test score. CATALOG DESCRIPTION: Introduction to the analysis of data using descriptive statistics, probability, and inferential statistics. Topics include: data collection methods; measures of center and variation; graphical presentation of data; probability; binomial and normal distributions; confidence intervals; hypothesis tests of one and two parameters, using the normal, Student-t, and chi-square distributions; linear correlation and regression. REQUIRED TEXT AND MATERIALS: This course uses Open Educational Resources, meaning all material will be made available to you at no cost. I will provide instructions on accessing the material in the course. The primary textual material for the course is the free Statistical Reasoning course offered by Carnegie Mellon University as part of the Open Learning Initiative. It is available at You have the option of registering for the course or just entering it without signing in. The only difference is that if you register, the system will help you keep track of where you are in the course. Other no-cost reading and tutorial material will be introduced during the course. You will need to install two pieces of software to do your homework. One is R, which can be downloaded from The other is RStudio, which can be downloaded from Both of these are available under public license at no cost. This will require you to have administrator privileges on your computer. Your computer will need to have either full Windows or OSX. Tablets running Windows/RT or ios will not be adequate. Chromebooks are also inadequate. COURSE GUIDANCE:

Treat others as you would like to be treated, respectfully and compassionately. STUDENT OUTCOMES: Upon successful completion of this course, you should be able to: Descriptive Statistics Probability 1. Demonstrate appropriate use of statistical terms. 2. Identify and describe various sampling methods. 3. Identify components of experimental and observational studies. 4. Identify uses and misuses of statistics. 5. Construct appropriate representations of data, such as tables (contingency tables and frequency distributions), and graphs (histograms, scatterplots, and boxplots), with and without technology. 6. Interpret and analyze various representations of data. 7. Calculate measures of center (mean, median, mode) with and without technology. 8. Calculate measures of variation (range, standard deviation, variance) with and without technology. 9. Identify various distributions (such as normal, uniform, skewed). 10. Understand and use probability vocabulary in context. 11. Calculate probability for simple and compound events using both empirical data and sample spaces.

3 12. Select and use appropriate counting methods (fundamental counting rule, permutations, combinations). 13. Identify defining characteristics of discrete probability distributions. 14. Solve problems using discrete probability distributions, including binomial distributions. 15. Determine the mean and standard deviation of discrete probability distributions. 16. Identify defining characteristics of continuous probability distributions. 17. Solve problems using continuous distributions including uniform and normal distributions. 18. Apply the Central Limit Theorem to calculate the mean and standard deviation of sampling distributions and use these to solve probability problems. Inferential Statistics 19. Determine appropriate sizes of samples. 20. Generate confidence intervals for means and proportions. 21. Select and perform hypothesis tests for the mean of one population, proportion of one population, means of two populations, and proportions of two populations. 22. Use the chi-square distribution to perform a hypothesis test such as goodness-of-fit or test of independence. 23. Analyze two-variable data using scatter plots, linear correlation coefficients, and linear regression lines, using technology to calculate these items. 24. Determine whether there is a statistically significant linear correlation between two variables. Communication and General Skills 25. Communicate the results of data analysis clearly and precisely in both technical and non-technical words, including the use of the following: correct statistical vocabulary; graphical, symbolic, and numeric support for conclusions; indications of the strength and limitations of conclusions. 26. Engage in experiential learning of key concepts through classroom activities and/or projects. 27. Draw logical conclusions related to a specific problem by integrating the use of the following: sampling; summary statistics and presentation of data; and either confidence intervals, hypothesis tests or regression analysis as appropriate. COURSE REQUIREMENTS: The main sequence of the course is divided into eight two-week modules, each of which requires a similar set of activities in order: 1. Read and work through the assigned material in the CMU OLI course. 2. Complete the assigned tasks embedded in the reading material and submit a document demonstrating your successful completion. 3. Read and work through the lecture notes written by the instructor. 4. Take the quiz before the deadline, which is midnight on the second Sunday of the module.

4 II. There are three lab assignments, which cover multiple modules. Instructions for these labs will be distributed during the course. GRADING: Each assignment and assessment will be given a specific point value. The earned value of all possible points will determine grade, per Pierce College published policy (see the Policies and Procedure section) WEIGHT OF ASSIGNMENTS/ASSESSMENTS: Component # per module # per course Value Reading Assignments (100 pts. each) 1 per module 8 per course 800 pts total Quizzes (100 pts. each) 1 per module 8 per course 800 pts total Labs (200 pts. each) NA 3 per course 600 pts total Total points for all course work = 2,200 points. Note: Divide your total points by 2,200 to calculate your percentage grade. GRADE SCALE: Pierce College records all grades with the GPA scale ( ) and does not assign letter grades. The highest possible grade is a 4.0, which would be considered an A by most colleges. The lowest passing grade is a 1.0, which would be considered a D- by most colleges. The percentage grade that you earned will be converted to a GPA grade. To make this conversion, a score of 100% (2,200 points) is considered the equivalent of a 4.0, and a score of 60% (1,320 points) is considered the equivalent of a 1.0. Intermediate scores are converted to the GPA scale using the following formula based on stating the percentage score as a decimal number between 0 and 1.0. GPA = 7.5 * Percentage 3.5 EXTRA CREDIT: There will be an assignment, similar to a lab, released near the end of the course. It will be worth a maximum of 150 points. The formula for converting to a GPA grade will remain the same, but with extra credit, the percentage grade could be greater than 100%. The maximum possible grade will still be 4.0. COURSE SCHEDULE: You will accomplish each module's learning objectives, which align with the course outcomes, by completing the readings and assessments as listed in the schedule, below. 1 Exploratory Data Analysis: 1 Variable CMU Slides 1-33 Begins 7/11/2017 Ends 7/23/ ,3,4,5,6,7,8,9,25,26 2 Exploratory Data CMU Slides Begins 7/18/2017 Ends 7/30/2017 3,4,5,25,26,27
