Data Strolling

I am not sure what this is at the bottom. Even though I use .head I still do not understand why there is not a value in there. I will do more exploring tomorrow with this.

Exploring the NSFG data

I am starting to learn more here about how to explore data. I am having trouble on getting the solution to submit as correct even though when I run the code it seems that I executed the assignment.

Clean a variable

The solution is below. It turns out I was missing a set of parathesis.

# Replace the value 8 with NaN
nsfg['nbrnaliv'].replace([8], np.nan, inplace=True)

# Print the values and their frequencies
print(nsfg['nbrnaliv'].value_counts())
