F. Technique of Data Analysis
The writer used a survey method through correlation technique.
She analyzed the research by using Product Moment Correlation to know the result.
Product Moment Correlation is one of technique that usually used to find out the significance of the correlation between two variables. This technique was published
by Karl Pearson, therefore it often called by Pearson Correlation Technique. It is called by Product Moment Correlation because it is usually used to correlate one variable to

The last step of this research methodology is analyzing the data. This analysis is to see and to find out whether there is significance correlation between students’
Intelligence Quotient IQ score and their achievement in learning English. And to find out the result of this research, the writer analyzed the data by using Pearson’s Product
Moment Correlation, as follow:
= .

∑ − ∑
Note: rxy
: Correlation coefficient between IQ score and English Score N
: Number of respondents X
: Distribution of students’ IQ score Y
: Distribution of Students’ English score ∑x
: Total score of students’ IQ distribution ∑y
: Total score of students’ English score distribution ∑xy : Total number of Multiple between X score and Y score
: Guaded from X : Guarded from Y
Significant critical value : 0.05 and 0.01
Criteria: If rt means there is correlation and Hα is accepted, Hо is rejected. If rt means there is no correlation and Hα is rejected, Hо is accepted.

H о
: There is no correlation between students’ Intelligence score and students’ achievement in learning English.
Ha :

G. Technique of Data Collecting
In collecting the data, the writer came to counseling teacher BK in MAN 19 to get the data of students’ IQ score. And then, to collect students’
English score, the writer asked permission of the English teacher to give the students English test.
