# Z-score in the analysis of data

I am being provided z-scores of dependent and independent variables. I was checking if it can analyzed as such as raw data?

Yes. This is how you get standardized regression coefficients. Here is another discussion of them. Basically, the point is to remove the unit of measure from the variable. When you only have one predictor in your model, your standaridized regression coefficients are equivalent to correlation coefficients. A 1 standard deviation increase in your $x$ variable leads to a $\beta$ times 1 standard deviation increase in your dependent variable. When you have more than one predictor, the interpretation is similar, but it is a marginal effect. So a change of 1 SD in your predictor leads to an expected change of $\beta$ times 1 SD in your dependent variable, assuming all the other variables in your model are held constant.
