The independent t ratio is used to test the difference between two means, and it specifies how much the difference deviates from an assumed mean of zero, in units of estimated standard errors of difference. This means that the t ratio allows us to determine if the difference between the sample means is statistically significant, after taking into account the amount of random variation that could be expected due to chance.
