Comparing language conversion rate (II)

Next, you want to look at the conversion rate by the language that the marketing asset was shown in. While many of your users speak English, some prefer another language. Let's check to make sure marketing material translated well across languages.

You can analyze metrics by specific demographics using .groupby(). Rather than looking at the overall conversion rate in the dataset, you instead group by language preference, which allows you to determine whether the marketing campaign was more effective in certain languages.
