Here's a question I've been struggling to put into words to explain:
If I'm doing a multiple regression, how can the regression model be statistically significant if only 2 of the 8 independent variables are significant?
What do you think?

if 6 of the 8 variables are insignificant, then their b coefficients are very low, i.e., they have very little effect on the dependant variable. in other words, the equation will yield roughly the same result whether you include those variables or not.
think about it. if your six insignificant variables have b coefficients of 0, then they do not change the predictive ability of the equation whether they are included or not.
does that help?
