Konnichiwa!

In this Blog, I'll explain both how big of a difference all of those things I mentioned in my Blog, "Getting Pokémon with High Stats" can make, as well as explain how you can tell what Stats Pokémon would have at different Levels, which can be VERY useful to know, especially if you plan on using those Pokémon in Battles where all Pokémon have their Level adjusted to 50.
(Like in the Battle Tower/Frontier/Subway/Maison/Tree, as well as in most Multiplayer Battles.)

I'll start of by showing you the formulas for calculating Stats, which I got off of Bulbapedia.

This one is for calculating HP:

And this one is for the other Stats:

Now, if you're not that good at Multplication, or just have a bit of trouble reading it for some reason (like me, no doubt due to my lousy Homeschool Education), then allow me to explain what all of that means.

Basically, you take those "Base Stats" that they list for every Pokémon, on websites like Bulbapedia and Serebii, and then double it, divide it by 100, and then multiply it by your Pokémon's Level.

Then, you add 5 to it, or if your calculating HP, you add 10, and then 1 additional HP per your Pokémon's Level.
(This is why Pokémon like Ditto, Phione and Mew always have higher HP, even though their Base Stats are all even)

Now, that's how you can figure out the lowest possible Stats a given Pokémon can have (not taking into account their Nature), but what about the highest possible Stats?

Well, each individual Stat on each individual Pokémon has an Individual Value (IV for short) associated with, which is why 2 of the exact same Pokémon with the exact same Natures can have VERY different Stats, even if you just caught them, and they're the same Level.

These "IVs" can range between 0 and 31, and at Level 100, you get 1 point per each IV in each Stat, whereas at Level 50, you get 50% of that, and at Level 30, you get 30% of that, and so on.

Effort Values (EVs for short), which I mention in my High Stats Blog, are the result of Training your Pokémon, and work similarly to IVs.

You get 1 point in each Stat per each 4 EV you have int that Stat, at Level 100, and like with IVs, you get a percentage of that, equal to your Pokémon's Level.
(That's probably why you can only take Pokémon up to Level 100, because you get 100% at Level 100.)

The following are Stats for 6 different Level 50 Rayquazas:


The 1st Picture shows 6 different Rayquazas that were just caught, and haven't been Trained yet, while the 2nd one shows their Stats after Training them to have 252 EVs in Attack and Sp. Attack, and 6 in Speed.

Rayquazas A, B, and C have the highest IVs in every Stat (31), while D, E, and F have the lowest (0).

A and D are Mild Nature, which raises Sp. Attack, and lowers Defense, while B and E have a neutral Nature (like Hardy), that doesn't affect Stats, and C and F have an Impish Nature, which lowers Sp. Attack, and raises Defense.
(The Stats shown in red are being raised by the Pokémon's Nature, and the ones shown in blue are being lowered by it, similar to how they show it in-Game.)

These are those same Rayquazas' Stats after Mega Evolving:


As you can see, the IVs, EVs, and Natures can have a HUGE impact on the Stats of a Pokémon, even a Super Powerful one like Mega Rayquaza, with Mega Rayquaza A having 255 Sp. Attack when fully Trained, while the untrained Mega Rayquaza F only has 167 Sp. Attack, even though they're the same Species of Pokémon, at the same Level.

Now, these are the Stats of a Timid Ditto (with Max IVs), so you can see how Level affects Stats:


Ditto has Base Stats of 48 in everything, and this one has had it's Sp. Attack EVs Maxed out, so you can see how much higher it is than it's Defense and Sp. Defense, which weren't Trained.

This is a Phione, which has a Base Stat of 80 in everything, with the same Nature, EVs, and IVs as the Ditto:


By looking at its Stats at Level 50, you can see clearly the impact everything has on it's Stats, including the Training in Sp. Attack (again, compared to Defense and Sp. Defense, which weren't Trained), the effect Nature has on it's Stats (Attack being 10% lower, and Speed being 10% higher), as well as the difference between it and the Ditto's Stats (32 points higher in everything at Level 50).
