We’ve inaugurated our MoE Machine, an online margin-of-error calculator designed by Langer Research Associates to assist data producers and empower data consumers in computing margins of sampling error in survey results. The program reports the MoE for any sample size, as well as the differences in a single sample, or in two independent samples, needed to achieve statistical significance. It allows for the inclusion of the design effect caused by weighting, an element of sampling error often disregarded in publicly released surveys. See it here, or click MOE in the menu bar on our homepage.
