The primary goal of UX design is to create products and services that are easy to use, efficient, and enjoyable for users.

A/B testing is a method for comparing two different versions of a product or service to see which one performs better. It is not a UX research method because it does not involve collecting data from users.

Interaction design is the process of designing the way that users interact with a product or service. It involves creating prototypes, wireframes, and other artifacts to help visualize and test the user experience.

Usability is a subset of user experience. Usability refers to the ease of use of a product or service, while user experience refers to the overall experience that a user has when interacting with a product or service.

The goal of usability testing is to collect feedback from users on the ease of use of a product or service. This feedback can be used to improve the design of the product or service.

Iterative design is a software development process, not a UX design principle. UX design principles are general guidelines that can be applied to any type of product or service.

A user persona is a fictional character that represents the target audience for a product or service. It is used to help designers understand the needs and wants of the users.

A prototype is a working model of a product or service that can be used to test the design and functionality. A wireframe is a static representation of a product or service that is used to visualize the layout and structure.

Accessibility in UX design is important because it ensures that a product or service is easy to use for people with disabilities. This includes people with visual impairments, hearing impairments, cognitive impairments, and physical disabilities.

Net promoter score is a customer loyalty metric, not a UX metric. UX metrics are used to measure the usability and user experience of a product or service.

The purpose of a heuristic evaluation is to identify usability problems in a product or service. This is done by using a set of predefined criteria to evaluate the product or service.

Jira is a project management tool, not a UX design tool. UX design tools are used to create prototypes, wireframes, and other artifacts to help visualize and test the user experience.

A closed-ended question has a limited number of possible answers, while an open-ended question has no limit on the number of possible answers. Closed-ended questions are often used to collect quantitative data, while open-ended questions are often used to collect qualitative data.

User research is important in UX design because it helps designers understand the needs and wants of the users. This information can then be used to create products and services that are tailored to the needs of the users.

Carousel is not a common UX design pattern. It is a type of content slider that is often used to display multiple items on a single page.
