When integrating data from multiple sources, you notice significant variations in currency values. What is the best approach to standardize these data for accurate analysis?

  • Consult with data owners to determine the correct currency for each dataset and apply conversions accordingly.
  • Develop custom algorithms to adjust currency values based on historical trends.
  • Ignore the currency variations as they may not impact the analysis significantly.
  • Use conversion rates to standardize currency values to a common currency during the transformation phase.
Standardizing currency values from multiple sources is crucial for accurate analysis. Using conversion rates during the transformation phase ensures consistency by converting all currency values to a common currency, facilitating comparison and analysis across datasets.
