difference between sample size and variance how to determine what the delta for a data set is why is variance necessary for a sample how to find the variance in a sample how much data should be allowed to vary when a data set b is allowed to vary by a tenth of its observation count what is normal delta for data set a which sample size is affected by variance which term best describes the range of data sets to vary the same per month? which of the following is an appropriate threshold for data set variation? what is the delta month over month for data set b how much variance can be used for data sets what is the delta for variance in a sample does data set b have more observations why would we allow data set a to vary a statistical threshold is established for how much deviation how much should data set b vary determining delta of variance for data set how much is the delta in month over month? what is the 3% delta in variance
