Study Notes
Hypothesis Testing Fundamentals
- The null hypothesis (H0) posits that there is no effect or no difference, serving as the default or starting assumption in hypothesis testing.
- The alternative hypothesis (Ha) indicates the presence of an effect or difference, suggesting that observed outcomes are not due to random chance.
Statistical Analysis Software
- SPSS (Statistical Package for the Social Sciences) is highlighted as one of the most widely used software packages for conducting statistical analysis.
Study on English Audiobooks and EFL Learners
- In examining the effects of English audiobooks on EFL (English as a Foreign Language) learners’ listening comprehension, the null hypothesis (H0) could state that there is no significant improvement in listening comprehension scores for learners using audiobooks compared to those not using them.
- The alternative hypothesis (Ha) would suggest that using English audiobooks significantly enhances the listening comprehension skills of EFL learners compared to those who do not use audiobooks.
