You can also find the total pairs by this formula: N(total pairs) = n(n-1) / 2, where n = total observations (8). For example in this problem: 8(7) = 56 56 / 2 = 28 making N = 28.

Hi Study Force, Greetings from Puerto Rico. This video was really helpful. I don't know if I misunderstood, but I think that in minute 5:45 you misplaced the X and Y values. For example, 230 was a Y value but was placed alongside the slope coefficient, while 421 was a X value, but was placed in the dependent variable (Y)... Maybe I misunderstood, but anyways this video was very helpful... This was the best video on the topic that I found on UA-cam.
Hi José, thanks for pointing that out. The good news is that α being 24.6362 is correct, in the sense that it comes from x and y being placed in their respective place! Therefore, the process and numbers moving forward are all correct -- just demonstrated that instance wrong :(

@@StudyForceOnline This video was great! Thanks for sharing your knowledge on UA-cam. Keep it up!
Came here expecting a very esoteric presentation, but was pleasantly surprised by the very clear explanation. Nice job!
Thanks a ton! This helped me conceptualize the method much more than the books I was looking at, awesome work.
A very good video. Thank you!
You guys make it so easy to learn! After reading countless pages, I watched this video and it all made sense. thank you!
EXCELLENT lesson!!! CongratulationA
This was amazing.

Thx man, that was a great job. I think if you use more visualization and less text, it'll improve your work
