Find the measures of central tendency (mean and median) for the two variables: "Insured.age" and "Credit.score". Discuss the shape of these two distributions. (provided already)

Which measure of central tendency is the best to represent the "Credit.score" data: the mean or the median? (Hint: Use 10% rule.) Discuss your rationale for the choice?

I just need the bolded question answered with details as to why the mean or median is best, what is the rationale? Please and thank you!

Here is the statistical data:
