Dear Grande i got confused on interpreting the beta coefficient in regression where dependent variable had been transformed to normal by inverse transformation.
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?
Please mention the video where you have normalised the data with zero and negative values.

q.no.2

Thanks for your clear explanation. Can the data be inversely transformed in excel simply by a formula of 1/data???
