Hello What does the chi2-Value 0.29 mean ? Does it also mean, that There is no significant diffrence ? Or does this value say, that There is a significant relationship between the variables and the survival ?
I think it is about difference in survivorship between the "two treatments" (which might also be treatment vs. non-treatment instead of two treatments?). But the video certainly did not help to figure this out.
Yeah, this is all kinda confusing. You have "a data set of 100 people", but, e.g., case 1 seems to have failed after 21 months. How does the fail variable then give 4? Did that person fail 4 times at once? Later on you explained that it's "the number of people who experienced that event at a certain fail time", so a case is not a person anymore. I'm more confused after the video than before.
Generally, it all feels very improvised. Did you know that you can actually have a script/outline before recording? You can even rerecord the video if there's unneccessarily confusing stuff like with the labels in the video.

Thanks so much for the clear explanation
