Normality and homogeneity test were analyzed by using SPSS 20.0 software of statistics. Furthermore, for calculating the normality test,
this study used Kolmogorov-Smirnov technique. After conducting normality and homogeneity test, the research was
continued by hypothesis testing. The hypothesis testing presented in this study because the purpose of the study was to compare and prove the correlation exists
between to variables that can give impact to the result of one variable. Hypothesis testing is “a procedure for making decisions about results by comparing an
observed value of a sample with a population value to determine if no difference or relationship exists between the values.

As stated by Emzir above, inferential statistic was used to analyze the variance or ANOVA One Way Analysis of Variance formula. In this study,
ANOVA was used to test the significant differences presented among students’
reading comprehension score based on their learning styles, visual, auditory and kinesthetic.
The formula of ANOVA is:
F = MS
