AGSC 137 involves the application of procedures and techniques for collecting, analyzing, and interpreting agricultural data. The course encompasses an introduction to statistical methods using examples and applications to which students can easily relate.  The course also focuses on teaching students basic statistical analysis using the MS Excel spreadsheet program and other pertinent computer tools.  Students enrolled in AGSC 137, which is part of the laptop curriculum, will be introduced to these important concepts through lectures and exercises that they may complete on their laptops.  Emphasis will be placed on providing the student with problem-solving skills and the ability to interpret the results of basic agricultural statistical analysis.  Following a brief introduction to statistics and statistical inference, students enrolled in AGSC 137 are introduced to common measures of central tendency and dispersion used in summarizing agricultural data followed by an introduction to the main concepts of probability and probability distributions and their potential applications in agricultural sciences.  Additional topics to be covered include random sampling, confidence intervals, hypothesis testing, correlation analysis, and linear regression (simple and multiple).

Prerequisite: MAGN 101 or equivalent
3 credits* (3 lecture hours), spring semester

* Credits do NOT count if a student successfully completes MATH 123.


At the successful completion of AGSC 137, the student is expected to have developed the skill to:

  1. Analyze and evaluate problems that involve descriptive statistics, probability distributions, random sampling, confidence intervals, hypothesis testing, correlation analysis, and linear regression as related to agricultural science.

  2. Understand the types of problems in agriculture that can be analyzed statistically.

  3. Utilize statistical concepts to interpret agricultural data.

  4. Use MS Excel effectively to analyze data and solve problems.


The instructor has the following designated office hours per week:

If necessary, students are also encouraged to make appointments to see the instructor at other times.


AGSC 137 is a three-credit hour course.  It includes three contact hours per week for 15 weeks.  One section of the course is offered during the 2018 Spring semester.  The schedule of the offered section is as follows:

Any student who feels s/he may need an accommodation based on the impact of a disability should contact the Disability Services (DS) office immediately to register for services and receive a Notification of Disabilities form. Once you have this form, we will meet privately, to discuss your specific needs.   Although you may register for services at any time, please attempt to make arrangements within the first two weeks of the semester so all appropriate academic accommodations can be set. 



Evaluation is a shared responsibility between the teacher and the student. The purpose of the evaluation is to demonstrate how well the professor has taught and the student has learned specific course materials, the principles, concepts, and terms relevant to the covered topics.  Evaluation is also intended to assess the student's ability to utlize the acquired knowledge and how s/he can use this knowledge in problem-solving.

The breakdown of grading in this course will be as follows:

The distribution of grades in this course will be based on the A-F College grading scheme. The letter grades correspond to the following percentage scale: A (90-100%), A- (87-89.9%), B+ (83-86.9%), B (80-82.9%), B- (77-79.9%), C+ (73-76.9%), C (70-72.9%), C- (67-69.9%), D+ (63-66.9%), D (60-62.9%), and F (<60%).
