- In this video, we explore two statistical problems: first, we calculate the Spearman's rank correlation coefficient between baseball team attendance figures in 1969 and 1971, revealing how closely related the rankings are between the two years.
Then, we apply a paired t-test to determine if there is a significant difference in pre-test and post-test scores, showing the effectiveness of a teaching method.
Follow along as we walk through each step of these calculations, demonstrating how rank correlation and hypothesis testing are used to analyze real-world data.
