graphically presented in the figure below.
Figure 4.1 The Profile Plots of the Listening Comprehension Mean Score
Based on the profile plots above, it can be seen that there is significant main effect for both independent variables learning technique and listening strategy.
However, the two lines are parallel. It means that there is no interaction effect. Whenever the lines are parallel, an interaction is not present. Interaction means
that the effect of one variable depends on the level of other variable being considered and this would produce non-parallel lines Johnson and Christensen,
2012: 307. Therefore, in the graph above interaction effect is not present. Students who are taught using FLAP always performed better than those taught
using Non-FLAP technique regardless of the listening strategy levels more varied or less varied, indicating a main effect of learning technique.
Based on the profile plots above, it can also be seen that students with more varied strategy taught using FLAP shows higher achievement in the listening
comprehension test than those who are taught using non-FLAP technique. Other comparisons can also be observed from the plots. However, the table below
probably can show in more detail the comparison of listening comprehension score in each group of students who have certain level of strategy taught by using
certain level of learning technique.

Each cell of the table above contains the mean score of students’ listening comprehension. Although the mean seemsto be different each other, it is still
unclear where the difference lies. Therefore, a further analysis using Post Hoc test is necessary to be conducted. Since the sample sizes are the same, I used Tukey
Post Hoc Test . The results are presented in table of multiple comparison below.
