It is remarkable that the sum of squares of the residuals and the sample mean can be shown to be independent of each other, using, e.g. Basu's theorem.That fact, and the normal and chi-squared distributions given above form the basis of calculations involving the t-statistic:

[ 5 ] In another example of a mixed-mode approach, the 2010 U.S. Census primarily relied on residential mail responses, and then deployed field interviewers to interview non ...

Some academic journals, particularly in the medical space, require minimum response rates to publish survey research as a means of mitigating non-response bias. For instance, JAMA has implemented a requirement of a 60% response rate for survey research, which has been compared to other heuristics like 0.05 p-values for statistical significance ...
