Which of the following is an example of a hard skill?

Hard skills refer to specific, teachable capabilities or knowledge sets that one can quantify. They are typically gained through education, training, or specific experiences. Data analysis is a prime example of a hard skill because it involves using statistical methods and software tools to interpret and manipulate data, requiring a concrete understanding of mathematics, statistical theory, and specific analytical techniques.

On the other hand, the other options represent soft skills, which are more about interpersonal abilities and personality traits. Teamwork and communication facilitate collaboration and interaction with others, whereas empathy involves understanding and relating to the emotions of others. While these are crucial for many career paths, they differ from hard skills in that they are less quantifiable and often involve personal disposition or social capabilities rather than technical proficiency.
