The article introduces new ways to estimate the average of a population by using information from two different sources, even when some data is missing. By combining data from two auxiliary variables, the researchers developed more accurate estimators for the population mean. These new estimators were compared with traditional methods and were found to be more reliable. The study also included real-world data to demonstrate the effectiveness of the proposed estimators.
