Adathibák

Adathibák, often translated as data errors or data flaws, refer to inaccuracies, inconsistencies, or invalidities present within a dataset. These errors can arise from various sources, including human mistakes during data entry, faulty data collection instruments, software bugs, or issues during data transfer and processing. Identifying and rectifying adathibák is a crucial step in data analysis and management, as they can lead to flawed conclusions, incorrect decisions, and unreliable results.

The types of adathibák are diverse. They can include missing values where data should exist, duplicate entries that artificially inflate counts, inconsistent formatting that makes data difficult to compare (e.g., different date formats), out-of-range values that fall outside expected parameters, or logical inconsistencies where data contradicts itself (e.g., an age of 200 years). The impact of these errors can range from minor inconveniences to significant problems depending on the context and the scale of the data.

Addressing adathibák typically involves a process of data cleaning. This can involve manual inspection, automated detection algorithms, and the application of validation rules. Strategies for correction may include imputation (filling in missing values), deduplication, standardization of formats, or removal of erroneous records. The goal is to ensure the integrity and quality of the data, making it suitable for its intended purpose.
