Let me clarify this. In my previous role, I was tasked with analyzing sales data to identify trends that could help improve our marketing strategy. I collected data from various sources and used Google Sheets to organize and validate the information. By applying pivot tables and charts, I was able to visualize the data effectively. This analysis revealed a significant increase in sales during certain months, which correlated with specific marketing campaigns. Based on these insights, I recommended focusing our efforts on similar strategies during those peak times, which ultimately led to a 15% increase in sales in the following quarter. This experience taught me the importance of data-driven decision-making in optimizing business outcomes.
