Hi, I want to perform multiple regression analysis with 5 IVs and 1 DV. First, I did correlation analysis. Four of my IVs are correlated with DV, but one of them is not correlated with DV in correlation analysis.

When I put all the predictors in the regression model, the model is significant. In addition, uncorrelated variable is also correlated with DV in regression analysis.

Is that possible or how can I solve this problem?

Also, can I add uncorrelated variable with DV in regression model?

Thanks for your help.
