GENERAL COURSE DESCRIPTION:
AGSC 135 is the first of two onecredit courses in the laptop curriculum of Agricultural Science involving the application of agricultural statistics and computers in research. The course encompasses an introduction to statistical methods to agricultural science students 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 135, 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 problemsolving skills and the ability to interpret the results of basic statistical analysis.
Following a brief introduction to statistics and statistical inference, students enrolled in AGSC 135 are introduced to common measures of central tendency and dispersion used in summarizing data followed by an introduction to the main concepts of probability and probability distributions. Towards the end of the semester, students enrolled in AGSC 135 will be provided with key material on sampling and sampling distributions.
