Learning Outcomes for AMS 110, Probability and Statistics for the Life Sciences
(Most of the material in AMS 110 is similar to AMS 102 but covered in greater depth.)

1.) Describe and apply the process of statistical investigations from conception through conclusion, with particular emphasis to life science applications.  This process involves:
     * Formulating questions and collecting data;
     * Analyzing data and drawing inferences;
     * Interpreting results and communicating conclusions.

2.) Demonstrate facility with, and a solid conceptual understanding of, the key tools of data analysis, including:
      * histograms; 
      * box plots, stem-and-leaf plots and other graphical displays;
      * measures of central tendency;
      * measures of dispersion.

3.) Demonstrate knowledge of elements of probability and key probability distributions, including:
      * probability of an event, sample space, equi-probable outcomes;
      * conditional probability and Bayes’ theorem;
      * binomial distribution;
      * normal distribution
      * chi squared distribution.

4.) Demonstrate facility with, and a solid conceptual understanding of, the key tools of statistical inference, including: 
      * z-scores;
      * estimation of intervals;
      * testing hypotheses, including Type 1 and Type 2 errors.

5.) Perform important statistical procedures, such as:
       * z-test;
       * t-test;
       * the chi square test;
       * linear regression.

6.) Work with technology to:
      * analyze data graphically; 
      * analyze data numerically; 
      * analyze data inferentially.

7.) Decide which statistical methods to use in which situations:
       * Recognizing which statistics tests apply in a situation;
       * Checking the necessary conditions for those methods to be valid.

8.)  Use statistics to address the biomedical research question at hand.
        * Interpret the results of statistical analyses to answer the research question;
        * Communicate conclusions that follow from the statistical analyses of the question.

9.)  Demonstrate an appreciation of the power and scope of statistical thinking for addressing research questions in a variety of scientific disciplines and in everyday life.
