Assumptions
This study assumes that there might be obvious difference between two teaching methods,
since the university should be motivated and study better through an interesting learning way
of role play.
Limitations
The study might be limited because the first part of the vocabularies might be much more
trouble-free then the second part of the vocabularies in the textbook. The students might be
able to become skilled at the first part better no matter what treatments had applied on them.
Results of Statistical Analysis
The objectives of this study were to measure the effects of two periods of vocabulary
training and distinguish which session is more successful. This passage reports the results of
the
data analysis, according to the statistical methods of T-test and two means comparison
through box plots. The t-test assesses whether the means of two
groups are statistically
dissimilar from each other. This examination is fitting whenever the researchers need to judge
against the means of two groups.
Moreover, the box plots (also known as a box-and-whisker diagram or plot) is a
convenient way of graphically depicting groups of numerical data through their five-number
summaries (the smallest observation (sample minimum), lower quartile (Q1), median (Q2),
upper quartile (Q3), and largest observation (sample maximum). A box plot may also indicate
which
observations, if any, might be considered outliers. (Wiki, 2009). In this study, the
researchers applied two graphs of box plots to simply compare
two means of teaching
vocabularies with interactive approaches and without interactive approaches.
