In statistics, a mixed-design analysis of variance model, also known as a split-plot ANOVA, is used to test for differences between two or more independent groups whilst subjecting participants to repeated measures.

ANOVA gauge repeatability and reproducibility is a measurement systems analysis technique that uses an analysis of variance (ANOVA) random effects model to assess a measurement system. The evaluation of a measurement system is not limited to gauge but to all types of measuring instruments, test methods, and other measurement systems.
On July 21, 2023, the OMB delineated four combined statistical areas, eight metropolitan statistical areas, and 12 micropolitan statistical areas in Oregon. [1] As of 2023, the largest of these is the Portland-Vancouver-Salem, OR-WA CSA , anchored by Oregon's largest city, Portland and including its capital, Salem .
This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.
