An analyst wants to create a historical data set for the past five years with each year in its own data set. Which of the following methods is the best way to create this historical data set?
The best method to create a historical data set with each year in its own data set is B. Data concatenation.
Explanation:
Data concatenation involves combining multiple data sets together sequentially. In this scenario, the analyst would create separate data sets for each year (2020, 2021, 2022, 2023, and 2024). Then, they would use the concatenation function to join these data sets together, forming a single, large data set with all the historical information organized by year. This approach allows for easy analysis and comparison of data across different years.
