What type of field should be used for coding a single choice value in Relativity?

The selection of a radio button is the most suitable choice for coding a single choice value in Relativity. Radio buttons are designed specifically for scenarios where users must select one option from a limited set of choices. This attribute is essential for maintaining the integrity of data input, as it prevents users from making multiple selections, which could lead to ambiguity in the data being collected.

Using radio buttons also enhances user experience by clearly signaling that only one selection is permissible, allowing for a straightforward and intuitive interaction. This is particularly important in legal document review, where precision in data categorization is crucial. The design of a radio button provides a clear visual representation of all the available options, making it evident to the user that only one can be picked.

In contrast, other options like drop-down lists, check box lists, or text input do not serve the same purpose as effectively. A drop-down list is useful for presenting multiple options without cluttering the interface but can sometimes lead to confusion about the selection if not properly labeled. Check box lists allow the selection of multiple values, which contradicts the requirement for a single choice. Text input could lead to variability in responses and lacks the structured options needed for coding categorical data.

Thus, radio buttons strategically fulfill the requirement for single
