Population vs Sample. The main difference between a population and sample has to do with how observations are assigned to the data set. A population includes all of the elements from a set of data. A sample consists one or more observations drawn from the population.
This sample difference between the female mean of 5.35 and the male mean of 3.88 is 1.47. However, the gender difference in this particular sample is not very important. What is important is whether there is a difference in the population means. In order to test whether there is a difference between population means, we are going to make three assumptions: The two populations have the same variance. This assumption is called the assumption of homogeneity of variance.
