# Explore the baseball data

Because the mean and median are so far apart, you decide to complain to the MLB. They find the error and send the corrected data over to you. It's again available as a 2D Numpy array `np_baseball`

, with three columns.

The Python script in the editor already includes code to print out informative messages with the different summary statistics. Can you finish the job?
