**Learning Outcomes for AMS 102, Elements of Statistics**

1.) Describe and apply the process of statistical investigations from conception through
conclusion. 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.

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:

* t-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 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.
