ICPSR webinar on weighting and variance estimation

New ICPSR webinar on October 4:

Weighting and Variance Estimation in Early Care and Education Data: A Training and Q&A

On October 4th, 2012, Research Connections will hold a Webinar training on using weights and estimating variances when analyzing data from national surveys with complex sampling designs. This Webinar will provide participants with a foundation for determining which weights to use for a particular analysis and how to apply them. It will also review the different options that are available for calculating standard errors for complex sample designs. The training will begin to answer the following common questions about weighting and variance estimation, as they relate to prominent data collections in the field of Early Care and Education:

-What are sampling weights and why are they important?
-Why should I use weights in my analyses?
-Why are there so many different weights in the datasets?
-Can I use weights with my statistical software package? How?
-Why are variances and standard errors important?
-What are design-based variance estimation methods and why should I use them?
There will be ample time after the presentation for live Q&A with the presenter. The conversation will continue through the end of the week via a question and answer blog, at which Webinar registrants and the data experts can continue the Q&A. Jerry West, Senior Fellow at Mathematica Policy Research, will be presenting.

Date: Thursday, October 4, 2012
Time: 1:00 - 2:15 pm EDT
