what is the difference between a mean and standard deviation definition of difference in standard deviation when a distribution has the same mean value as a sample? if two distributions of a data have the same mean value and a standard deviation of sample 1 is twice the value of sample 2, explain what the difference in standard deviation would indicate about the two distributions of data. what would happen if a standard deviation was twice the mean of a two sample sample significance of a test what is significant in a statistical analysis if mean and standard deviation are alike what would a difference in mean and standard deviation in data indicate why is the standard deviation of a test so important? what is the standard deviation of the same test which question is considered significant in a statistical analysis what would the difference between a standard deviation and a standard deviation indicate? if i compare two samples what should the standard deviation indicate about the two distributions? why is standard deviation twice the mean in a difference what does a standard deviation represent in a test? what is the difference between standard deviation and mean what would a difference in standard deviation in a standard deviation test mean what is the difference in standard deviation of a standard deviation sample 2 what would the difference in standard deviation mean about a standard deviation in a data set mean? what is meant by difference in standard deviation in data which question is a significa
