Dear Dr. Wicklin,

I am currently working with real student data, which includes the following variables: age, gender, high school GPA, first-term GPA, and second-term GPA. However, I have observed that the variables representing first-term GPA and second-term GPA exhibit left skewness. My goal is to generate a new dataset that maintains the covariance structure and means similar to the original dataset while ensuring that it closely mimics the statistical characteristics of the real data. Could you please suggest the most effective technique for achieving this?

Thank you for your guidance.

Sincerely,
Abdullah
