SOUTHWEST COLLEGE –STAFFORD CAMPUS Department of Mathematics Statistic Course Syllabus Math 1342, CRN #46458: MTWTHFs: 10:30AM –12:30PM SW Hub. 223 Summer II 2013 INSTRUCTOR Ernest Nwachukwu CONTACT PHONE # EMAIL ADDRESS (713) 718 7770 Ernest.Nwachukwu@hccs.edu Attendance policy: Students are expected to attend classes regularly. If some special situation arises, which calls for your missing classes, then please keep me informed. If I am not notified and your absences exceed 12.5% of the number of classes, you will be administratively withdrawn immediately. Tardiness (lateness to class) policy: Every student is expected to be in class on time. If a student is late on the examination day, the student will not be given extra time. Withdrawal policy: Any student who is contemplating withdrawing from the class is encouraged to do so on or before the final day for withdrawal. The final day for withdrawal is on the HCC schedule. If astudent withdraws after the final day for withdrawal, the student will get an “F”. Home Work policy: Assignments will be given every week but usually will not be collected. For a student to get the best out of this class, it is very important that the student solves problems in the textbook. If a student fails to do assignments, it is not likely that the student will pass the examination. Exam Policy: Cheating is not allowed in the examination. If a student is caught cheating in an examination, the student will lose all the marks for that examination. College policies on cheating will be enforced. These are clearly outlined in the HCCS Student Handbook. Make-up policy: There will be no make-up of any test. An exception to this can be allowed if there is a case of medical emergency and with a valid proof. There will be no make-up of the final examination. Grading policy: Each of the first four examinations is worth 20%; and the final examination is worth 40% of the final course grade. The final course grade (call it FCG) will be calculated using the formula:FCG = Average of the best five grades (final counting double). Letter grade will be assigned to the FCG. Grade legend: 90% - 100% - A, 80% - 89% - B, 70% - 79% - C, 60% - 69% - D, below 60% - F. Final Examination : The final examination consists of 33 multiple-choice problems. The problems cover only the material required in this course. Catalog Description: MATH 1342 Statistics. Topics include histograms, probability, binomial and normal distributions, and their applications, correlation and prediction, and tests of statistical hypotheses. Prerequisite: MATH 1314 or its equivalent or an acceptable placement test score. 3 credit (lecture). Prerequisites: MATH 1314 or its equivalent or an acceptable placement test score. BEGINNING OF SEMESTER ADVISEMENT Students are advised about the pre-requisites for the above class and how they are related to their major and the next class to take in mathematics. END OF SEMESTER ADVISEMENT Students are advised on the future courses in mathematics and how they are related to their majors. All questions were answered. FINAL GRADE OF FX Students who stop attending class and do not withdraw themselves prior to the withdrawal deadline may either be dropped by their professor for excessive absences or be assigned the final grade of “FX” at the end of the semester. Students who stop attending classes will receive a grade of “FX”, compared to an earned grade of “F” which is due to poor performance. Logging into a DE course without active participation is seen as non-attending. Please note that HCC will not disperse financial aid funding for students who have never attended class. Students who receive financial aid but fail to attend class will be reported to the Department of Education and may have to pay back their aid. A grade of “FX” is treated exactly the same as a grade of “F” in terms of GPA, probation, suspension, and satisfactory academic progress. EGLS3 -- Evaluation for Greater Learning Student Survey System At Houston Community College, professors believe that thoughtful student feedback is necessary to improve teaching and learning. During a designated time, you will be asked to answer a short online survey of research-based questions related to instruction. The anonymous results of the survey will be made available to your professors and division chairs for continual improvement of instruction. Look for the survey as part of the Houston Community College Student System online near the end of the term. Course Intent: This course is intended for students primarily in health sciences and business rather than math or science majors. It consists of concepts, ideas, and utilization using statistics rather than a theory course.
