Course schedule

Math 214 meets Mondays and Wednesdays, 18:30 to 20:10. Monday is theory, Wednesday is computer lab with practice.

Textbooks

We will be using the OpenIntro Statistics open textbook (free ebook; $25 at Amazon), and The Book of R ($40 ebook; $50 on paper).

In the schedule below, we will abbreviate these as OIS for OpenIntro Statistics and BoR for The Book of R.

Dec 18 Final Exam

Project 1

Pick a dataset from our collection, write a report describing the dataset comprehensively. Your report should contain appropriately chosen graphs, descriptions of observed descriptive statistics of the available variables in the data, and an evaluation of the experiment and sampling design in the data collection.

Due dates

A draft of the first report is due October 11.

First report is due October 18.

As a support for formulating hypotheses, you will read an assigned co-students’ report and suggest ideas to them according to the report you read. These ideas are due October 25.

You then need to formulate your hypotheses and register them with me through Blackboard. Your hypotheses are due October 30.

A draft of your report for feedback, as with the first report, should be submitted November 29.

Your report is due through Blackboard timestamped no later than 14.30 on December 6.

Project 2

Based on the report from Project 1, suggest a number of hypotheses for what the dataset could indicate. With the larger sample from the same source made available for Project 2, write a report evaluating your hypotheses and testing them. Report your inferential results both with confidence intervals and with significance levels.

Final Examination

The final will be a computer lab session focusing on using and interpreting results from RStudio. There will be an opportunity in the final that allow you to raise your grade by up to two minor grade steps: for instance, raise from a B to a B+ or an A-.
