(This is just an excuse to do a dinky little statistical analysis. Because I’m feeling analysis-deprived tonight.)
Long ago (2011) I took a series of online quizzes to figure out when the internet thought my average age of death was (which is a super valid prediction method, right?). Because I’m bored and have no life whatsoever, I’ve decided to re-take those same quizzes today and see if there is a statistically significant difference in the mean age of my death according to the internet.
Year2011 year2015 86 87 70 67 79 79 90 84 89 89 85 85 91 90 85 85
Method: Since this is me just repeating a bunch of tests I’d taken before, this calls for a paired t-test!
H0: there is no difference in the means for 2011 and 2015
Ha: there is a difference in the means for 2011 and 2015
Results: The difference of the sample means is 1.125. With t = 1.3864, p-value = 0.282, we do not have significant evidence to reject the null hypothesis that there is no difference in the means for 2011 and 2015
Basic conclusion: My average lifespan (according to the internet) has neither increased nor decreased since 2011.
Sorry I’m so boring.
