Statistics 219

STAT 219: Statistics for Biology

Prerequisites: None

Credit Hours: (3)

This course is an introduction to statistical methods taught by embedding statistical language and methods into a biological context. Topics will include univariate and bivariate graphs; measures of average, dispersion, and position; estimation; hypothesis testing; correlation; regression; analysis of variance.

Note(s): Students may not receive credit for both STAT 219 and STAT 200. This course has been approved for Core Curriculum credit in Mathematical Sciences College Core B.


Detailed Description of Content of Course

additional work that will be required of students taking the course for graduate credit.

I. Scientific method

II. Data collection

        a. Observational studies

        b. Experimental designs

III. Descriptive Statistics

        a. Graphical methods for displaying biological data

        b. Measures of average, spread, and location

        a. Binomial

        b. Poisson

V. Continuous Probability Distributions

        a. Normal

VI. Statistical Inference

        a. Point and Confidence Interval estimation

        b. Hypothesis Testing

        c. Analysis of Variance

        d. Simple Linear Regression

        e. Nonparametric Tests


Detailed Description of Conduct of Course

Classes will be conducted in lecture format with time reserved for discussion. The students will be required to use current technologies, such as graphing calculators and JMP statistical software, for some of the assignments, so a few of the class periods (2-5) will serve as laboratory sessions in preparation for these assignments.  Examples taken from labs in biology core courses will be used to introduce the application of statistics to biological topics wherever possible and appropriate.  Small groups may be formed to work on in-class projects.  Students will be assigned problems to work for homework.


Student Goals and Objectives of the Course

Having successfully completed this course, the student will be able to:

1) describe biological data using graphs and statistics

2) discern the type of statistical test appropriate for different biological problems

3) conduct statistical tests on biological data

This course meets the requirements of supporting skills and knowledge of the core curriculum (College Core B).


Assessment Measures

Students will be assessed with homework using textbook problems, computer projects, and in-class exams.
