why is it that the variance is high on mobile scores what is data set variance at what value of mean and variance should I throw data away? calculating the mean variance what would the variance be of a small data set which data set has high mean and variance what is the measure of variance what is mean variance at what value of variance should i throw data away? when does a variance occur in a data set? why should i throw away data? what is a data set when i calculate variance of a sample of a data set, i throw away what data set has the highest variance why is variance considered to be a data set how to compute the variance in a data set can we throw data away at what value is variance supposed to be rejected by a data set? why is my data set considered a large data set what is the average value of the variance
