As a player, do I use Stone Edge on my Tyranitar or Rock Slide? In Pokemon, there are high damage moves with low accuracy, but there are also lower damage moves with higher accuracy. I will analyze this case from two viewpoints: mathematical and situational.
Introduction
Let's suppose that you were building an OU team and decided to use a Scarfed Mixed Salamence. As soon as that happens, the impossible questions begin to pop up. Do I use Fire Blast or Flamethrower? Stone Edge or Rock Slide? Give up now or give up later? Stone Edge may be necessary for you to get an OHKO, assuming you can land a hit. Flamethrower is very consistent, but perhaps the damage output just isn't enough. In Pokemon, there are high damage moves with low accuracy, but there are also lower damage moves with higher accuracy. Which move should the player use? This article answers that question by exploring two viewpoints: mathematical and situational.
Mathematical Viewpoint:
Mathematics and probability are our treasured friends when answering this question. They allow us to calculate the expected damage output over a long period of time. I'm going to get into some mathematical jargon here, so if you're not interested, you can skip this part and look at the calculated rates below. In theory, if a move is used 100 times, that move will hit the opponent the number of time equal to its accuracy. So, if you take a move's base power, multiply it by the number of times it's expected to hit out of 100, you will get the total expected damage output. I WILL GO ON WITH THIS SECTION.
Expected damage output (when used 100 times)
Stone Edge: 8000 (Base Power 100. 80% Accuracy. 80 hits out of 100. 100x80)
Rock Slide: 6750 (Base Power 75. 90% Accuracy. 90 hits out of 100. 75x90)
Rock Tomb: 5700 (Base Power 60. 95% Accuracy. 95 hits out of 100. 60x95)
From a purely mathematical standpoint, Stone Edge is the better option because it has a higher expected damage output.
Scald / Surf / Hydro Pump
Flamethrower / Heat Wave / Fire Blast
Thunderbolt / Thunder
Ice Beam / Blizzard
Fighting move / High Jump Kick

Situational Viewpoint:
When we look at a battle from a situational viewpoint, we may realize that one move may be preferred over the other.
Rock Slide / Rock Tomb vs. Stone Edge
When we looked at it mathematically, Stone Edge was the superior option because it had a higher expected damage output. However, what if we looked at a battle from a situational viewpoint. Suppose that its the end of the game, and all you have is your scarfed Landorus-T against a Zapdos with half if its HP left. Can you afford to miss with Stone Edge? That move only has an 80% accuracy. What this means is that out of ten battles where you're in this situation (or similar), you're only mathematically expected to win four out of those eight battles. However, if Landorus-T used Rock Slide instead of Stone Edge, which has a 90% accuracy, you're mathematically expected to win nine games out of those ten. You're expected to win one more of these games when you use Rock Slide instead of Stone Edge.
Consistency
Etc.
Flamethrower vs. Heat Wave vs. Fire Blast
Scald / Surf vs. Hydro Pump (Keldeo)
Thunderbolt vs. Thunder
Thunder's accuracy is too low to be consistent.
Ice Beam vs. Blizzard
Fighting move vs. High Jump Kick
