Brief Description:

The aim of this course is to provide an easy introduction to inference through a series of practical applications. Once you have completed this course you will be able to test hypotheses regarding a simple regression or a comparison of proportions or two means.

Instructor(s):
Level: Novice/Refresher

Who Should Take This Course:

Anyone who encounters statistics in their work, or will need introductory statistics for later study. The only mathematics you need is arithmetic (see below for basic prerequisites).

Introduction to Statistics 2: Inference and Relationships

Last session of this course is May 4th.  For subsequent sessions, please register for Statistics 2 - Inference and Association.

Aim of Course:

To provide an easy introduction to inference through a series of practical applications, using resampling (simulation) methods. Once you have completed this course you will be able to correctly analyze studies with paired data, and test hypotheses regarding a simple regression, a comparison of proportions or two means, or a contingency table with count data.

Note: This is the third of a four course sequence, part one being Intro Stats (beginner), and part two being Introduction to Statistics 1: Sampling and Inference.

Teaching statistics, especially AP statistics? The summer session of this course is especially suited to AP stats teachers who need to tune up their statistical skills.

Prerequisite(s):

Introduction to Statistics 1 : Sampling and Inference

If you are unclear as to whether you have mastered the requirements, try these placement tests here.

Course Program:

SESSION 1: Hypothesis Tests

• Hypothesis tests for a single sample
• Departure from expected (chi-square)
• Hypothesis tests for more than two samples
• Null and alternative hypotheses
• One-way and two-way tests

SESSION 2:  Association and Relationships

• Is there a relationship?  Correlation vs. association
• Measuring linear correlation with the correlation coefficient
• Non-linear association
• "Correlation is not causation"
• Linear regression

SESSION 3:  Regression

• Regression residuals
• Inference for regression
• Reviewing software output

Organization of the Course:

This course takes place over the internet at the Institute for 3 weeks. During each course week, you participate at times of your own choosing - there are no set times when you must be online. Course participants will be given access to a private discussion board. In class discussions led by the instructor, you can post questions, seek clarification, and interact with your fellow students and the instructor.

The course typically requires 15 hours per week. At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Discussion among participants is encouraged. The instructor will provide answers and comments, and at the end of the week, you will receive individual feedback on your homework answers.

Credit:
Students come to the Institute for a variety of reasons. As you begin the course, you will be asked to specify your category:

1. You may be interested only in learning the material presented, and not be concerned with grades or a record of completion.
2. You may be enrolled in PASS (Programs in Analytics and Statistical Studies) that requires demonstration of proficiency in the subject, in which case your work will be assessed for a grade.
3. You may require a "Record of Course Completion," along with professional development credit in the form of Continuing Education Units (CEU's).  For those successfully completing the course, 3.75 CEU's and a record of course completion will be issued by The Institute, upon request.

Course Text:

All reading materials will be provided online in PDF or other electronic format.
