why can the difference between the mean and the standard deviation which statement best describes the importance of comparing mean and standard deviation what is the significance of mean values different in two processes why is the difference between means different why would the standard deviation of two mean values be different? when a true value is different, how to determine the significance what is the importance of the standard deviation in an experiment what is the probability of different mean values how to find the likelihood for a different mean can the resulting mean values be different can mean be different why do n mean different if a value is different from one measurement in one experiment how to determine the confidence when two means are different what is the test how to find the standard deviation of the mean a measurement is different how to tell if mean is different how to determine the importance of different means how to test for the difference between the standard deviation and mean _______________________ does not change the mean for an experiment. can you measure a mean change in two processes
