What case should you always use when programming a survey?

When programming a survey, using a consistent case—particularly mixed case—enhances readability and helps in maintaining a professional appearance in your survey design. Mixed case allows the text to be presented in a way that is conventional for most languages, making it easier for respondents to read and understand. It is particularly useful for labels, instructions, and questions, as it closely resembles natural language usage.

Using uppercase for all text can lead to readability issues and may feel overly aggressive or shout-like in tone, which is not conducive to a pleasant user experience. Conversely, relying solely on lowercase can come across as informal and may be difficult for respondents to parse in longer texts. Positive case is not a recognized programming practice in this context, so it does not apply to the conventions typically recommended for survey design. Consistency in casing throughout the survey also aids in data collection and analysis, avoiding potential confusion in interpreting variables and responses.
