You now know how to use numpy functions to get a better feeling for your data.
It basically comes down to importing numpy and then calling several simple functions
on the numpy arrays:

import numpy as np
x = [1, 4, 8, 10, 12]
np.mean(x)
np.median(x)
The baseball data is available as a 2D numpy array with 3 columns (height, weight, age)
and 1015 rows. The name of this numpy array is np_baseball. After restructuring the data,
however, you notice that some height values are abnormally high. Follow the instructions
and discover which summary statistic is best suited if you're dealing with so-called outliers.

Instructions
-Create numpy array np_height that is equal to first column of np_baseball.
-Print out the mean of np_height.
-Print out the median of np_height.

# np_baseball is available

# Import numpy
import numpy as np

# Create np_height from np_baseball
np_height = np.array(np_baseball[:,0])

# Print out the mean of np_height
print(np.mean(np_height))

# Print out the median of np_height
print(np.median(np_height))
