Perception
Perception is used to increase the speed in which water production rooms (Water treatment, water purification) and determines the speed of the critical hit indicator, higher perception decreases the speed the indicator moves, allowing you to get high critical hit damage more easily. In the wasteland it helps you to find locations.

Endurance
Endurance is used to increase the speed in which the Nuka Cola Production Plant creates food and water. It is also the assigned skill for the storage areas and determines how many hit points dwellers get as they level up. Endurance can be increased in the fitness room. It is also your survivability in the quests or wasteland.

Charisma

Intelligence
Intelligence is used by medbays and science labs. In can be trained using the classroom.

Agility
Agility is used in food production rooms (Diner and Garden). It also determines how fast dwellers fire their weapons. Agility can be increased using the athletics room. In quests or the wasteland it determines how many shots you can fire before the enemy does.

Luck
Luck is not used by any rooms but does determine if dwellers make extra caps during rush attempts, the success chance of rush attempts, as well as chances of finding items when you go out on quests and explore locations in the wasteland. The higher the luck, the better the items.
