Aggregate Pokémon by Types
First, mean attack power is compared across various types of Pokémon: Each Pokémon can be of multiple types, so first you need to form all valid Pokémon-type combinations using CombinedEntityClass. Then group by type and compute the mean attack for each type. Finally, sort by attack.
Similarly, you can explore the mean speed of Pokémon grouped by colors.
Finally, Pokémon characters are grouped by the first letter of their Japanese names and their mean total power is compared.
