THANK YOU!!! You just literally changed my life, and saved me from going insane. I've been doing problems by hand all semester. I used to hate Excel but now I'm its biggest fan. Thank you!
I just stumbled upon this channel and I am so amazed and grateful! Thank you so much for sharing your knowledge! I wish there were more people like you! THANK YOU SO MUCH
Thank you! You are a great teacher. I have a question on my homework about the degrees of freedom for the t test of the regression coefficients. I’m still unsure of that
Hi, thanks for the video, it is very helpful. I have question regarding the t-stat. So it is not important that the t-stat is positive or negative, because excel is using a two tailed t-test in the regression? so as long the p value is under 0.05 for alpha = 5% then the coeff. is significant right?
That is correct. We don't pay attention to the sign of the t-stat. If p < .05, the coefficient is significant in the regression analysis. The sign of the coefficient, on the other hand, is very important.

Thank you! You are a great teacher. I have a question on my homework about the degrees of freedom for the t test of the regression coefficients. I’m still unsure of that
The degrees of freedom for the t is N - # of predictors - 1.

Thank you so much for this lecture!
Thank you, Sir 👍 good lecture & really helpful 😍
I'm glad you found it useful.
Should it be the older the people, the fewer people like Justin B. since the slope coefficient is minus?
More precisely, we should say that the negative coefficient indicates that the older the people in the sample were, the less they liked Justin Bieber.

@@DavidDunaetz thank you so much sir
talk about the t-stat!
The t stat is calculated from the standard error. It's the statistic that it used to determine if the coefficient is significant or not.
@@DavidDunaetz what would the degrees of freedom for it be?
The degrees of freedom for the t is N - # of predictors - 1.
