Attributes are the core stats of a character that determine things like the skills you can get, your success chances for certain abilities or your ability to resist certain ailments.
Your attribute modifier for each attribute is determined by (attribute value-16)/2, rounded down. Your attribute modifiers are used to determine roll bonuses in the respective attribute. They be increased in multiple ways. The easiest way is to level up, as specific levels grant you plus one to all stats. Additionally specific levels can give you an attribute point which you can spend to increase a specific attribute. Some mutations can increase Strength, Agility, and Toughness as well. Consuming an Eater's Nectar Injector has a chance to randomly increase one of your attributes (although these are rare and expensive.) Lastly, specific items or randomized relics can increase attributes. this bonus is applied/removed immediately when equipped/unequipped.
If you gain attributes at a later point any gains you would have gotten since level 1 are awarded immediately (intelligence:skill points, toughness:max hp) with no loss to total skill points/attributes.
Creatures other than the player character also have the same attributes, and theirs function the same way.
"Your strength score determines how effectively you penetrate your opponents' armor with melee attacks, how much damage your melee attacks do, your ability to resist forced movement, and your carry capacity."
Strength is important for a lot of melee characters, as it determines the Penetration Value for most melee weapons. You get extra PV equal to your strength modifier when using melee weapons, up to the weapon's maximum PV value - early-game weapons have a low PV cap, which reduces the utility of very high strength values until later in the game. It will also let you carry heavier equipment to raise your Armor Value to decent levels to compete in late game; you have 15 pounds of carrying capacity for every point of strength.

"Your agility score determines your accuracy with both melee and ranged weapons and your ability to dodge attacks."
Agility is very useful for any melee or ranged character as it increases chance to hit. In order to hit an opponent, your d20 roll + agility modifier must be greater than the enemy's d20 roll + DV. For ranged attacks, this roll is also affected by the distance to the opponent and the weapon's innate accuracy; additionally, agility reduces ranged weapons' cone-of-fire, increasing the chance that their projectiles will pass through the tile of the targeted creature to be eligible to have a chance of hitting them in the first place. It also contributes to defence in the form of increasing Dodge Value.

"Your toughness score determines your number of hit points, your hit point regeneration rate, and your ability to resist poison and disease"
Toughness is very important stats as it affects the amount of Hit Points you get per level and some of the more useful skills are unlocked by having decent toughness. You can never go wrong with extra health.
A level 1 character's max hp is the same as its toughness. Leveling up increases your max hp by a random amount, but the average amount it goes up by will be proportional to your toughness. That means double toughness leads to twice as much of an increase to max hp. Toughness's influence on previous max hp increases is retroactive, so a character starting with high toughness will, on average, have the same max hp as someone of equal level who gradually built up to the high toughness.
Toughness and willpower determine your rate of health regeneration. Each point in your toughness and willpower modifiers makes you heal 2 more health every 100 turns. The exact formula for health regeneration is 20 + 2 * (Willpower Modifier + Toughness Modifier) health per 100 turns. At 16 willpower and 16 toughness, this is 20 health every 100 turns.

"Your intelligence score determines your number of skill points and your ability to examine artifacts."
Intelligence determines the number of skill points your character earns each time they gain an experience level. Having decent or high intelligence can help you survive more easily early on in the game as you can unlock important skills earlier. Not to mention that it helps to identify artifacts and create/modify them with the tinker skill. In addition, your intelligence is used to spot hidden threats, such as Young Ivories.
At 11 intelligence, mutants earn 50 skill points and true kin earn 70 skill points upon leveling up. Each point you are above 11 intelligence will increase how many skill points you earn on level-up by 4 (ex: a 12 intelligence mutant nets 54 skill points upon level-up). Just like with toughness and max hp, intelligence's influence on skill points is retroactive - your total earned skill points will act like you had your current intelligence during all previous level-ups. Oddly, 10 intelligence gives exactly the same number of skill points as 11 intelligence.

"Your willpower score determines the frequency with which you may use your mental mutations, your hit point regeneration rate, and your ability to resist mental attacks."
Willpower is useful for Esper/Esper-like mutants as it is required to lower cooldown on mental mutations. Each point of willpower above 16 (not each point of modifier, as with most other attribute effects, but each actual point of willpower) decreases your mental mutation cooldowns by 5%. This stacks additively to a maximum reduction of 80% at 32; willpower beyond that point will provide no cooldown benefit. Similarly, each point of willpower below 16 increases the length of your mental mutation cooldowns by 5%.
Willpower and toughness determine your rate of health regeneration. Each point in your toughness and willpower modifiers makes you heal 2 more health every 100 turns. The exact formula for health regeneration is 20 + 2 * (Willpower Modifier + Toughness Modifier) health per 100 turns. At 16 willpower and 16 toughness, this is 20 health every 100 turns.

"Your ego score determines the potency of your mental mutations, your ability to haggle with merchants, and your ability to dominate the wills of other living creatures."
Ego is another very important Esper/Esper-like mutants, because it can boost mental mutations over their level 10 cap. Other than that it is useful for extra profit when trading with merchants. This can be useful if you plan on investing skill points in Tinker II and Tinker III as higher tier data disks cost a lot.
The effects of Ego on merchant buy and sell prices are modeled below; note in particular that Ego yields diminishing returns for buy prices. An ego bonus above +9 (including the effective +2 from Snake Oiler, if applicable) has no effect. Note that this means that Snake Oiler will eventually become useless for completely Ego-focused builds.
