I've noticed that a lot of the same questions come up over and over again on the forums.
We used to have a dedicated Tutorials subforum before the Great Forum Kraken devoured everything from after October 2012, but it seems that most of what's left has been scattered around a bit.My props to the forum staff to restoring the Tutorials section. Still, there are some quite good references scattered all over the internet that some people who only browse the forums might not be aware of. Therefore, I've decided to share a few links to what I consider some of the best Kerbal Space Program tutorials and resources I've been able to find.
Of course, it's still a work in progress, as I'm sure I've missed quite a lot of good information. I'm willing to take suggestions, but keep in mind that I prefer links to full-fledged tutorials or charts with hard data over regular discussion threads (although I'm sure many of those have a wealth of info as well). I'll also consider any suggestions y'all might have about how I can improve the formatting of the overall list to make it easier for people to find what they're looking for as well. I'll try to keep this updated fairly regularly.
That said, here's what I've gathered so far. If the contributor has multiple identities / names / user names / what-have-you, I've listed the one they use on the KSP forums first. Note that I tend to be a little slow on adding video tutorials, as my Internet service provider has a monthly bandwidth cap, and buying "bonus minutes" is expensive.

- Graphs of Engine Comparison Flights: By Dispatcher. Provide data on various forms of engine performance under certain conditions, taken from the same test flights used to compile the above comparison chart.
- Engine data: By ThePseudoMonkey. A set of charts comparing the performance of the game's engines, as well as showing their delta-v capability with different fuel loads.
- Mass-optimal engine type vs. delta-V, payload, and min TWR: By tavert. A series of charts that seeks to answer the question: "For a given delta-V and payload, which engine gives the lowest total craft mass?"
- Engine Cluster Calculator for KSP: By blizzy78. Use this calculator to determine how to most efficiently set up engine clusters and radial asparagus stages for your launch vehicles. Includes options to incorporate parts from certain popular mod packs, including KW Rocketry, NovaPunch, and AIES Aerospace.
- A detailed look at Kerbal's jet engines: By Iffn. A series of charts demonstrating the performance specifications of the various jet engines available in the game, with some analysis and commentary. Also available as an Imgur album here.

Real World Rocket Science References
- Atomic Rocketships of the Space Patrol: By Nyrath / Winchell Chung. An entertaining and informative website written to debunk many common misconceptions about space travel and give the "man on the street" knowledge of the basics in layman's terms. It's mostly geared towards real-world rocketry, but much of the information on basic orbital mechanics and rocket design can easily be applied to KSP.
- Rockets and Space Technology: By Robert A. Braeunig. An informative site containing a wealth of information about real-world space travel, including a tutorial on the basic principles of orbital mechanics and interplanetary flight (warning: math) and data on spacecraft.
- Akin's Laws of Spacecraft Design: By Dave Akin. Some practical words of wisdom from real-world rocket science, presented through tongue-in-cheek humor.
- Encyclopedia Astronautica: By Mark Wade. An exhaustive reference about real-world space travel, including vehicles, personalities, manufacturers, and other topics. Includes a large number of designs that never quite made it to the launchpad. You may find it useful for getting inspiration for your next big project.
- Roleplay tips for the realism inclined: Various authors. Want to challenge yourself by playing more "realistically," or just want to try out an interesting handicap because the game's gotten too easy otherwise? Check out some of these ideas.
