2. The Correlation between Students’ Motivation in Reading and
Reading Speed
After achieving the data of students’ motivation in reading as variable X and the score of reading speed as variable Y, the next step is determine the
calculation table, which is to be used as the calculation for the index score correlation of product moment.In this case, scores
of students’ motivation in reading and reading speed test are correlated by using Pearson Product Moment
formula. The data can be seen in the table 4.2 which the description is as follows: Based on the result
score of Students’ Motivation in Reading x and Reading Comprehension y the total score and the data can be seen as follows:
