What type of error does data bias typically create?

1. A fair representation of data

2. A systematic skew of results

3. An unbiased result

4. A random error

The correct answer is: A systematic skew of results

Data bias typically creates a systematic skew of results because it introduces consistent deviations in the data analysis process. When bias is present, certain outcomes or trends may be favored over others, leading to inaccurate or misleading conclusions. This systematic distortion occurs because the bias influences the way data is collected, analyzed, or interpreted, reinforcing a misrepresentation of the actual conditions or relationships within the data. In contrast, options that suggest a fair representation of data, an unbiased result, or random errors do not align with the nature of bias, which intentionally or unintentionally skews findings in a particular direction rather than presenting them neutrally or randomly.
