Learner Outcomes:

Upon completion of the course, the student will: use graphical and numerical methods to summarize and describe data. Demonstrate a basic understanding of probability and statistics. Describe and use different discrete and continuous random variables. Identify bivariate probability distributions, covariance and correlation and the probability distribution of a statistic. Perform estimation and hypothesis testing of population parameters

Units Outcomes and Clock Hours of Instruction for Core Curriculum:

  • Contrast one tailed vs. two tailed statistical tests.
  • Test population mean for large and small samples
  • Describe and calculate the observed significance level (p-value)
  • Test the difference between population means: independent large (small) samples with identical (different) population variances and matched pairs

Projects Required:



Statistics for engineering and the sciences, William Mendenhall and Terry Sincich, 6th edition, CRC Press/Taylor& Francis, 2016. Please Contact Bookstore for current textbook.

Materials/Equipment Required:

Graphing calculator (TI-83 or TI-84 series calculator)

Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

Grading Policy:

The grading policy will be outlined by the instructor in the course syllabus.

Maximum class size:

Based on classroom occupancy

Course Time Frame:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college.  A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time.  The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
