   How do you calculate the standard error of a difference?

   • The standard error se of the difference between the two means is calculated as: The significance level, or P-value, is calculated using the t -test, with the value t calculated as: The P-value is the area of the t distribution with n1 + n2 − 2 degrees of freedom, that falls outside ± t (see Values of the t distribution table).
