Null Hypothesis
In aviation, the null hypothesis refers to the assumption that there is no significant difference between two or more groups being compared. This hypothesis is tested using statistical analysis to determine if the observed differences between the groups are due to chance or if they are statistically significant. In aviation, the null hypothesis is often used in safety studies to determine if there is a significant difference in safety outcomes between two or more groups, such as pilots who have completed a specific training program and those who have not. If the null hypothesis is rejected, it means that there is a significant difference between the groups being compared.
