    Qno.1
    I have 3 dependent variables. Two of them are in range of normal skewness value i.e. +1 to -1 and have kurtosis in range of +3 to -3, but the third remaining dependent variable is not in normal range of skewnes or kurtosis. I want to transform that variable with square root transform to run parametric tests. So the question is, Can I transform that one variable only and run parametric test on the variables or I should transform all three variables before doing test? should I transform all three variables together even the two of them are already normally distributed? will it create problems to transform only one non normal variable?
    q.no.2
    Can I infer and interpret my data for normality on the basis of skewness and kurtosis only rather than gooing for shapiro wilk test?

    Sir Brandon, what if the data are still not normal after having the transformation?

    Hi, Could please cite the resulting CLRM (regression equation) after the transformation is done

    Sir, in case you wanted to plot that formula, would you refransformt he beta values?

    Hi Nice presentation. Thank you. I am wondering how you report the equation y=b + b1X1. Would you back transform the coefficients or would you write in your report something like sqrt(y)=2.837 +0.433(SpRichness)

    I was hoping to ask a question but seeing that you haven't replied anyone of the questions in previous comments, well...
