what is the t statistic for green and red what is the difference between blue and red in the t-std how to find differences with other variables in matlab what statistic indicates that blue and green are very different why is there overlap between two normally distributed variables how to show the overlap of two normally distributed variables what is the standard deviation for a graph of normally distributed variables average overlap in a distribution how much overlap in a distribution how do you measure the overlap between two normally distributed variables how to measure overlap how to determine difference in the standard deviation of blue and red how to find the overlap of the normally distributed variables what is the standard deviation for a normal distribution? what is the standard deviation for an overlap test how much difference in blue and red which variable does the t test show how many lines of r overlap different how can you tell the average overlap how do you tell if two pairs are slightly different
