UX Design Patterns
Software is often defined by what makes it different, but in many cases, the same UX and design problems appear over and over again; a pattern, across many applications. Rather than come up with a brand new solution for every problem - a solution that could require a tutorial to educate users - it's often best to turn to familiar solutions that a user will immediately recognize. These solutions are called design patterns, and when it comes to UX, these patterns can solve problems in the user interface and they can also help influence the behavior of users.

Wireframing
Wireframing is a process that should occur early on in a website or app design project. In the early stages of a project, you (as well as others on your team) will have a lot of ideas and the best way to sort through those ideas is to start brainstorming. Wireframes are a visual artifact of this brainstorming, and the goal is to make them with minimal effort, as to encourage ideation and minimize exerting unnecessary effort on a sub-par idea. Whether you're a designer, a prospective designer, or (more generally) a person with product or marketing ideas...wireframes are a valuable tool for visualizing user experiences, iterating on ideas, and sharing ideas with others.

Cleaning and Preparing Data
We rely on data to answer important questions, whether we are trying to make the best business decisions or determine the effectiveness of a new medical treatment. But our analyses are only as accurate as the data we are using, and incorrect or “dirty” data can lead to incorrect conclusions and assumptions. Data preparation, also called “cleaning” or “scrubbing”, is an important part of ensuring our analyses are accurate and useful.
