Course Description: A practical course in probability and statistics including such topics as the binomial and normal distributions, confidence intervals, t, F, and chi-square tests, linear regression and correlation, and conditional probability.

Text: The Basic Practice of Statistics, by David S. Moore. W.H. Freeman and Company, 2007.

Objectives: After completing MAT 131 the student will be able to

  • demonstrate understanding of the relationship between a question that is asked in the natural, economic, and social sciences and the nature of the numerical data that are needed in order to provide an answer to the question,
  • carry out the required algebraic manipulations, with appropriate use of a calculator, to analyze and understand the implications contained in a set of numerical data,
  • draw a valid inference from a collection of numerical data.

Prerequisites: Students must have satisfied the ELM requirement before enrolling in MAT 131.


Grades: Grades will be based on four in‑class 60-minutes examinations (60% total), a comprehensive final examination (25%), and quizzes, homework, attendance and other assignments (15%) for the remainder.

The exact grading system for your section is the following:

Each of the four 60-minutes exams will be graded on a 100 scale, then the sum of the best three scores is divided by 5 and denoted by E.

Homework will be due every class meeting, and each homework assignment is worth 5 points. No late homework will be accepted. The average of all homework scores is denoted by H.

5 to 10 minutes quizzes will be given in principle every day, with the exception of the review and exam days, and will be graded in class on a scale from 1 to 5. The average of the quizzes scores is denoted by Q.

There are also 5 points awarded for attendance and class participation. This portion of the grade is denoted by A.

The final exam will be graded out of a maximum possible 200, then the score is divided by 8 and denoted by F. 

To determine your final grade, compute E+H+Q+A+F. The maximum is 100, and the grade will be given by the rule:

         A: 93‑100;      A‑: 90‑92;      B+: 87‑89;      B: 83‑86;   B‑: 80‑82

        C+: 77‑79;      C: 73‑76;        C‑: 70‑72;      D: 60‑69;   F: Less than 60.



Makeup: No makeup examinations or quizzes will be given. If you must miss an examination for a legitimate reason, discuss this, in advance, with me, and I may then substitute the relevant score from your final examination for the missing grade.
