When adding different answer options to a question, you’re actually labeling them. This label can be text (very satisfied, male, not applicable, etc.) or a number (0, 18, 55, …).
When downloading the raw data with the Show labels option this is the label you will see in the corresponding cells.
For the following rating scale question, for example, you will see the actual wording “Not important at all” through “Very important” in the raw data.
