MATH-138 Statistics

In this course, students will develop the skills necessary to examine basic statistical terminology; develop pictorial and analytical distributions; and use statistical tables, a calculator, and a computer to calculate measures of central location and measures of variation. The student will additionally examine the normal distribution, correlation, and regression analysis, sampling, testing hypotheses, the chi square test and probability related to statistics. Classes will require use of a statistical computational package, stat-crunch.

MATH 070 (Intermediate Algebra) or higher or appropriate math placement score.

For purposes of verification and assessing learning outcomes, this course has three proctored unit exams and a comprehensive final exam at the HCC Testing Center for students in the local region or at a regional institution for remote students. The exam will have a flexible window of time during which it needs to be taken rather than a single date and time.
