even though the variable is important). The second problem is that the confidence intervals on the regression coefficients will be very wide. The confidence intervals may even include
High correlation among independent variables is sometimes suggested as a sign of multicollinearity.If the absolute value of the sample correlation between any two independent variables in the regression is greater than 0.7, multicollinearity is a potential problem. However, this only works if there are...

The variables listed first in the problem statement are the independent variables (ivs): "strength of affiliation" [reliten] and "frequency of prayer"...
It can be calculated using the df=N-k-1 formula where N is the sample size and k is the number of regression coefficients. SS (Sum of Squares): The Sum of Squares is the square of the difference between a value and the mean value. The higher the value of the Sum of Squares ...
A multiple regression analysis is a type of regression analysis wherein there are multiple independent variables. This stands in contrast to simple regression analysis, which contains only one independent variable. In multiple regression analysis, each independent variable is tested with the same ...

Although the “with training group” had a participant size much smaller for an appropriate multiple regression, the “no training group” had a participant size of 73 which sits just under the cut-off for sample size according to Stevens (2002). Regardless of this, the multiple regression...
