silence by lamguage limitations.
Speech is so halting and fragmentary
as to
make conversation virtually impossible.

Comprehension
Appears to understand everything
wighout difficulty.
Understands nearly everything at normal speed, although occasional
repetition maybe necessary.
Understands most of what is said at slower-than-normal speed with
repetitions.
Has great difficulty following what is said. Can comprehend
only “social conversation” spoken slowly
and with
frequent repetitions.
Cannot be said to understand even
simple conversational English. 5

F. The Technique of Data Analysis
To analyze the data, the writer used the comparative technique. She analyzed and compared the score of experimental class. This technique is useful to prove
statistically, whether there are any sifnificant differences between the students’ scores
of the experimental class and the students’ scores of the control class. In analyzing the data from pre-test and post-test of the two classes, the writer
used the statistical formulation of t-test formula.

= Test observation = Mean of Differences; the average score from the differences
gained scores between I variable and II variable, which are calculated with the formula;
∑ ∑
= Total score between I variable X variable and II variable Y variable.
And D is gained with the formula;
= Number of cases
= The standard deviation from diffrences between score of X variable, which is gained with the formula;
= √

= The standard error from mean of differences that is gained with the formula;

df = Degree of freedom with formula N-1
G. Statistical Hypothesis
To prove the hypothesis, the data obtained from the experiment class and the control class was calculated by using the t-test formula with the assumption as
follows:
t
o
t
t
: The alternative hypothesis Ha is accepted and the null hypothesis H
o
is rejected. It means there is significant difference on
students’ speaking achievement taught by role play”. It means that role play is an effective technique in teaching speaking.

: The alternative hypothesis Ha is rejected and the null hypothesis H
o
is accepted. It means there is no significant difference on students’ speaking achievement taught by using role play”. It
means that role play is not an effective technique in teaching speaking.
