When we test for differences between the means of two independent populations, we can only use a two-tailed test.
Independent Populations
Two or more populations that do not affect each other, such that measurements from one population are not related to measurements from the others.
Two-tailed Test
A statistical hypothesis test in which the area of rejection is on both sides of the sampling distribution, allowing for the exploration of the possibility that a parameter is significantly greater than or less than a specified value.
Means
The average of a set of numerical values, calculated as the sum of the values divided by the number of values.
