why not use $s2$ as an estimator is s2$ an estimator which is a good statistic is s2$ a good estimator? is $s2$ an estimator does n$s2$ represent a measure of spread is $s2$ a good estimator which is the best estimator for a measure of sample variance is $s2$ an estimate of the mean? is $s2$ an estimator is $s2$ the right estimator is $s2$ an estimator what is the value for s2$ is $s2$ an estimator which of the following is a measure of the spread of the test? is $s2 a measure of spread of a variable is $s2$ a measure of spread which formula is a measure of variance? why is $s2$ not a measure of spread? why? why is $s+2$ not a good estimator
