|INTRODUCTION TO SURVEY ESTIMATION
A short course sponsored by the Joint Program in Survey Methodology
MAY 1-2, 2017
Presented at the Bureau of Labor Statistics Conference Center
Senior Statistician and Vice President at Westat, Past President American Statistical Association
Associate Research Scientist at the Survey Research Center, University of Michigan
This short course provides an introductory exposure to producing estimates of population parameters from sample surveys. It will examine the uncertainty of estimates resulting from sampling, through presentation of how sampling errors of survey statistics vary as a function of sample design and weighting procedures.
The course discusses procedures for estimating descriptive statistics like means, percentages, population totals, quantiles as well as model parameters from sample surveys. It also examines statistical procedures used in comparing subgroups on attributes measured in the survey.
The course presents inferential issues that arise in moving from sample-based statistics to describing the target population of the survey. It also describes how to compute the sampling errors of survey estimates and how to make inferences from them to the population. It describes current practices in weight adjustments and in the presentation and description of estimates made from sample surveys. Practical exercises during the short course reinforce the lecture materials and handouts.
WHO SHOULD ATTEND
Researchers and analysts who need to produce statistical estimates based upon data collected via complex sample surveys and who need to make inferences about those estimates. The types of estimates to be discussed include: totals, means, percentages, quantiles and model parameters. The elements of complex sample designs to be examined include: unequal weights, clustered, stratified and multi-stage designs.
Attendees will benefit the most after the session if they have access on their job to software that computes sampling errors for estimates from complex survey data. Such software will be needed to implement the course concepts in their work. The course will provide an overview on software options.
