• Attendance: Seven absences results in withdrawal from the course. A late is one third of an absence. Thus any combination of absences and lates that adds to seven will result in withdrawal. For example, twenty-one lates would result in withdrawal.
• No betelnut in class nor on campus except in the cultural huts.
  No spitting over the balcony!
• Quizzes are given every Friday that there is not a test. Quizzes and tests can and do occur on a Wednesday wherein Friday is a holiday.
• Grading policy:
  Homework is worth 1 to 3 points.
  Quizzes are worth on the order of 5 to 10 points each.
  Tests are worth on the order of 20 points.
  The midterm is worth roughly 40 points.
  The final is worth up to roughly 60 points.
  The term as a whole will generate some 200 plus points.
  Grading is based on the standard College policy: Obtain 90% of the points or more to obtain an A, 80% to 89% for a B, and so forth.
  Points map to student learning outcomes via questions on publicly published quizzes, tests, and examinations wherein each question can be linked back to a course or program learning outcome. For further information refer to the student learning outcomes nexus:

• Academic Honesty Policy: Cheating on an assignment, quiz, test, midterm, or final will result in a score of zero for that assignment, quiz, or examination. Due to our cramped quarters, the course operates by necessity on a system of personal integrity and honor.

Course Description: A semester course designed as an introduction to the basic ideas of data presentation, descriptive statistics, linear regression, and inferential statistics including confidence intervals and hypothesis testing. Basic concepts are studied using applications from education, business, social science, and the natural sciences. The course incorporates the use of a computer spreadsheet package for both data analysis and presentation. The course is intended to be taught in a computer laboratory environment.

   Students will be able to:
   1. Calculate basic statistics (define, calculate)
   2. Represent data sets using histograms (define, calculate, estimate, represent)
   3. Solve problems using normal curve and t-statistic distributions including confidence intervals for means and hypothesis testing (define, calculate, solve, interpret)
   4. Determine and interpret p-values (calculate, interpret)
   5. Perform a linear regression and make inferences based on the results (define, calculate, solve, interpret)

Course Intentions

• Use of Microsoft Excel and Microsoft Excel functions (or spreadsheet software with equivalent statistical functions) throughout the course as opposed to using dedicated statistics software package. Excel and other spreadsheets will be the desktop software most widely available to MS 150 students both while taking the course and, more importantly, in the workplace post-graduation.
• Use of real-world data, examples, and problems to the extent appropriate and possible.
