What is a type of data that is typically expressed in words?

Qualitative data is a type of information that is expressed in words rather than numbers. This form of data captures characteristics, descriptions, and qualities that can offer in-depth insights into subjects or phenomena. It is often collected through means such as interviews, open-ended surveys, and observations, allowing for a nuanced understanding of participants' thoughts, feelings, and experiences.

Qualitative data is valuable in psychology and other social sciences as it provides context and depth to research findings, helping to uncover patterns and themes that numerical data may not reveal. For example, rather than just reporting how many people prefer a specific therapy, qualitative research might explore why individuals feel a certain therapy resonates with them, revealing motivations and personal stories.

The other options presented do not fit this description: quantitative data involves numerical values that can be measured and analyzed statistically; numerical data specifically refers to data represented by numbers; while descriptive data could be seen as a broad term that might include both qualitative and quantitative forms. However, when specifically identifying the type typically expressed in words, qualitative data stands out as the correct choice.
