Proportions

[oldoc63]

• We can use the .value_counts() function to get a table of frequencies for a categorical variable.
• However, it is sometimes more useful to instead look at the proportion of values in each category.
• We can calculate proportions by dividing the frequency by the number of observations in the data:

df['education'].value_counts()/len(df['education'])

• We can also calculate proportions using .value_counts() by setting the normalize parameter equal to True:

df['education'].value_counts(normalize = True).head()
