Im a little stuck here. In step 7 (Learn data science with Python and R projects) the instructions tell you to create a new function to convert certain values to True, False and NaN. All good so far. Then it says
’ Use the [
DataFrame.applymap() method] to apply the function above to the
'Contributing Factors. Dissatisfaction' and
'Contributing Factors. Job Dissatisfaction' in the
Now I don’t understand this because applymap() can only be applied to a dataframe and not to series, right? So, am I expected to create a new DF off of those two columns and then use applymap? Could anyone help me understand what’s expected here?
