I have a research and I use regression to analyze my data. first I input my datumn in spss and analyze those with regression. the result is all of independent variable are signifficant. then I try to compare my result with the data that convert to ln (logaritma natural. I convert the data of variable dependent to ln and so do the independent variable. but the result is difference. one of my independent variable is not signifficant.is it normal or actually the result must be the same?
