Sample Size using PASS software from NCSS

taught by Tom Ryan

Aim of Course:

This course will offer an introduction to sample size and power analysis using PASS (Power Analysis and Sample Size) software from NCSS, and will show how to use it simply and effectively to plan the appropriate sample size for a study. The power of a study (the study's ability to establish that a treatment effect exists) is determined by such factors as the magnitude of the treatment effect, the sample size, alpha (the level of statistical significance required), and (for survival studies) the study duration.

Prerequisite(s):

For those working in the life sciences, Biostatistics 1 may also be helpful.

Course Program:

SESSION 1: Introduction to PASS software from NCSS

• Review hypothesis testing and confidence interval construction
• Introduction to sample size determination and power for one mean and two means (variances assumed known)
• Retrospective power and labeling of effect sizes
• Introduction to PASS

SESSION 2: Power and Sample Size for Means and Proportion

• Sample size determination for one and two means with variances unknown and for confidence intervals
• Independent samples and paired samples
• One proportion and two proportions
• One variance
• Considerations in determining sample size: power, cost of sampling, ethics

SESSION 3: Power and Sample Size for ANOVA and Regression

• Sample size determination for most-often used statistical methods:
  • Analysis of Variance
  • Linear Regression
  • Logistic Regression
• Commonly used Experimental Designs, plus Repeated Measures designs

SESSION 4: Miscellaneous Topics

(students to study what interests them)

• Microarrays
• Clinical Trials
• Quality Improvement Methods
• Nonparametric Tests
• Equivalence Tests
• Multivariate Methods
• Survival Analysis and Reliability

 

HOMEWORK:

Homework in this course consists of short answer questions to test concepts and guided data analysis problems using software.

Organization of the Course:

This course takes place over the internet at the Institute for 4 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, 5.0 CEU's and a record of course completion will be issued by The Institute, upon request.

Course Text:

All necessary materials will be provided online.

Software:

Participants should have access to PASS software by NCSS. For those needing software, a trial will be made available for the duration of the course.
