The result of t-test by using paired sample t-test obtained result that on α = 5 % with DK ={t|t ≤ −t0.025;33 = −2,03 or t ≥ t0.025;33 = 2,03} and tobs = -7,29, maka –tobs = −7.297 ≥ −ttable = −2.034. And was obtained value Sig. (2-tailed)= 0.000 <0.05, therefore, it can be concluded that both groups have unequal achievement.
