Deduce MNAR
In the previous exercise, you worked on identifying the type of missing values given the missingness summary. In this exercise, you'll continue on that spree to affirmatively identify data that is Missing Not at Random (MNAR).
The missingness summary for the diabetes DataFrame is as below.
Your goal is to sort the diabetes DataFrame on Serum_Insulin and identify the correlation between Skin_Fold and Serum_Insulin.
Note that we've used a proprietary display() function instead of plt.show() to make it easier for you to view the output.
