    Hi,
    Sorry for that, but I think there is a wrong somewhere.
    Cell F12 in the sheet Model 1 that represent Significance F is: 4.6710E-6 which actually means: 0.000004671 which is very less than 0.05.

    Why is the P-Value in S13 too big? It's ~0.00000126 if I'm seeing it correctly

      i think she's talking about the 2.5 in second row p-value

    The entire regression table explanation seems to be incorrect. The p-value explanation is wrong.

    Please check the P-values 3:18 You are considering them more than alpha (0.05) which is wrong.

      Agree ........didn't take in effect what the E-06 does to the value.....and this is a Dr.

    1. MR alone does not mean anything, unless you have solid theoretical framework.
    2. On the contrary to what you have said, the p values appear to be less than 0.05.

    I am sorry to say this, but this video clip has a lot of inaccuracies. I strongly advise Dr. Debra to revisited the clip and make amendments or take it down.

    Dr Dean here should have her PhD rescinded after this video. Yikes

    Your P values are okay Dr Debra they are all less than 0.05, I think you didn't check the negative exponent

    The. p Value is much les then .05

    I thought that I would watch an educational video on the topic of multiple regression analysis to help me determine what variables influence stock performance in the market, but this video was littered with inaccuracies. The p-value analysis was wrong, as well as the Significance F analysis (p-value for the whole model), multiple values were E^-n, where n was some number denoting how many zeroes after the decimal place before the number to the left started. This would net p-values < 0.05 as long as n was >= 2 in the E^-n format. It was in many cases, and was disregarded as statistically insignificant, thereby rendering the whole analysis in the rest of the video useless. Please correct or takedown this video to avoid further confusion.
