DA0-001 · Question #63
Different people manually type a series of handwritten surveys into an online database. Which of the following issues will MOST likely arise with this data? (Choose two.)
The correct answer is A. Data accuracy F. Data manipulation. Manual data entry by different individuals significantly increases the risk of errors, leading to issues with both data accuracy and consistency across the dataset.

Why each option
Manual data entry by different individuals significantly increases the risk of errors, leading to issues with both data accuracy and consistency across the dataset.
Manual data entry is highly susceptible to human errors such as typos, misreading handwriting, or incorrect data entry, directly leading to inaccuracies in the recorded information.
Data constraints are rules applied to the database fields; while errors from manual entry might violate these, the constraints themselves are not the issue that arises from the manual process.
Data attribute limitations refer to the predefined scope or characteristics of data fields, which are set prior to data entry and are not an issue that arises from the manual typing process itself.
Data bias typically originates from the data collection method or the inherent characteristics of the data population, not directly from the transcription errors of manual data entry.
When multiple individuals manually enter data, their diverse interpretations of handwriting, application of varying formatting rules, or inconsistent choices in data representation can lead to unintentional alterations or transformations of the original data, which constitutes data manipulation.
