Abstract: Abstract In Chap. 2 , the one-sample t-test was introduced to test whether a single mean of a population is equal to a certain value. This chapter will introduce the extension of the t-test to examine whether the difference between two population means is equal to a certain value. Two situations will be discussed: the first is when the two means are from independent (i.e., unrelated) populations, and the second is when the two means are from related populations.
