2: the total of square score of students’ writing descriptive text ability The data was analyzed through some steps as follows:
1. Determining the scores of N, ,
, ,
2, and 2;
2. Determining and calculating the scores of r
xy
using Product moment correlation formula;
3. Interpreting the scores of r
xy
using the Table 3.1 below:
Table 3.1 Table of
r Score Interpretation

The r score scales
Interpretation of r correlation
0.800—1.00 very high
0.600—0.800 high
0.400—0.600 moderate
0.200—0.400 low
0.000—0.200 very low
4. interpreting and comparing the scores of r
xy
based on the significant standard 5 and 1;
5. drawing conclusion based on the interpretation of r
xy.
G. Statistical Hypotheses
The statistical hypotheses of this study are symbolized into: H
1
: ρ ≠ 0 or if r
xy
rt, H1 is accepted, and H0 is rejected; H
: ρ = 0 or if r
xy
rt, H0 is accepted, and H1 is rejected. The statistical hypotheses above may be explained as follows:
- Alternative hypothesis H
1
: there is any significant relationship between students’ vocabulary mastery and their writing descriptive text ability;
- Null hypothesis H
: there is no any significant relationship between students’ vocabulary mastery and their writing descriptive text ability.
