Microsoft Word Interactive Approaches for Vocabulary Te

T-test for comparing two groups of scores
Base on the T-test graph, the analysis demonstrated that a statistically significant 
difference between two means of pedagogy applications. From the graph of T-test and the 
graph of two box plots showing means, the results of two types of teaching vocabulary 
methods are significantly different. Through twenty-six students’ scores of two quizzes, the 
results showed that the different level of two means of 68.58 and 81.58 is 13 pints. From the 
significant number in the second graph we can see the p value close to zero which means the 
different level is significantly obvious. We recognize that small p-value (closer to 0) the 
stronger the evidence against the null hypothesis. That is to say, the Ho: Null hypothesis of no 
different is definitely rejected through the value on the statistic Graph II and Graph III.  
Box-plots for comparing two groups of scores
From the two displayed box plots, we are able to recognize that the obvious progresses of 
learning and teaching English vocabularies of students and the trainer had developed and 
presented in the language learners’ second quiz. In the first quiz of vocabulary the grade 
mean shows obviously lower than the second mean analyzed from the adult students’ second 
quiz of role play for practicing the usages of learned vocabularies. The interactive approaches

of vocabulary teaching and learning are proved to be useful since the students had orally 
practiced the learned words, so that they are able to memorize them, apply them and 
demonstrate their understanding the quiz of vocabulary.
