Sample Size Calculations NCSL Conference 24 August 2019

Great way to pick up RU’s for your ASQ Certification.

Topic: Sampling Course Career
Course Title: Sample Size Calculations

Course Catalog Number: Tme-3
Course Track: Metrology Engineers Course

Level: Intermediate
Saturday, August 24 | 8:00 AM – 5:00 PM | 1-Day (8 Hours)

Instructor: Paul Mathews, Mathews Malnar and Bailey Inc.

Abstract: Most situations that require the collection and analysis of sample data present the problem of determining an appropriate sample size. Small samples are more likely to lead to incorrect conclusions but large samples consume more resources. Formal methods of sample size determination are intended to minimize the combined costs associated with incorrect conclusions and resource consumption.Paul Mathews will present methods for calculating sample size for confidence intervals and sample size and power for hypothesis tests for: means, standard deviations, proportions, counts, regression, correlation and agreement, ANOVA for fixed and random effects, reliability, process capability, and gage error studies. Practical methods using large sample approximations, variable transformations, and the delta method will be emphasized but exact methods will be noted where the approximate methods fail. Paul will demonstrate software solutions using MINITAB and Russ Lenth's free Piface program ( workshop is intended for engineers, scientists, statisticians, and quality professionals who are responsible for recommending sample sizes in their organizations. Attendees should have a general understanding of the calculation and interpretation of confidence intervals and hypothesis tests. Knowledge of advanced statistical methods is not required.

Learning Objectives:

1.Understand the necessity for calculating an appropriate sample size before collecting any data.

2.Lead a client through a discussion to identify the necessary inputs to a sample size calculation prior to collecting data intended to be analyzed using a confidence interval or hypothesis test.

3.Calculate approximate and, where appropriate, exact sample sizes for confidence intervals and hypothesis tests for means, standard deviations, proportions, counts, linear regression, correlation, designed experiments, fixed and random effects in ANOVA, reliability studies, process capability parameters, and gage error studies.

ASQ Certification Point Thresholds changed

Notice of Certification Point Threshold Change

Based on member feedback, ASQ has increased the recertification unit (RU) point thresholds significantly, rewarding section and division activities. These changes were approved by the ASQ Certification Board in September 2016 and went into effect on January 1, 2017.

Specifically, the points increased are in the following categories:

– A. Points change, Section E/Meetings, from 9.0 to 10.8.

– B. Points change, Section F/Committees, from 6.0 to 8.0.

All changes are reflected in the online recertification application and the hardcopy Journal (see recertification-changes_2017.pdf]). For further details, please visit
