Feature exploration

Using the same Avazu dataset, you will explore how the values of device_type and banner_pos are distributed, as well as how CTR varies based on them.

Sample data in DataFrame form is loaded as df. The X and y variables that you created in the last exercise are available in your workspace. pandas as pd are also available in your workspace.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Distribution of values for device type
print("Distribution of device type: ")
print(X.device_type.____()/len(X))

# Sample CTR by device type 
print("CTR by device type: ")
print(df.____('device_type')['click'].____/len(y))
