Which statement is true regarding the number of bias types?

• A. Bias types are fixed and there is a universal number
• B. There is a universal number
• C. Different academic sources offering differing opinions regarding the number of types of bias that exist
• D. There are exactly seven types

Answer: (C)

The number of bias types isn’t fixed; different sources describe and categorize biases in varying ways. Some lists include many subtypes, while others group biases into broader categories, and new biases are discussed as research progresses. Because there isn’t a single authoritative catalog, there isn’t a universal count that everyone agrees on. That’s why the correct idea is that different academic sources offer differing opinions on how many biases exist. Fixed numbers like a universal count or a specific number such as seven don’t reflect how the field actually defines and groups biases.
