The appropriate statistical analysis for comparing means in a two-group design is the independent-measures t test. This test is used when the two groups are independent of each other, meaning that the participants in one group are not related to the participants in the other group. The t test determines whether the difference between the means of the two groups is statistically significant or simply due to chance.
