How Excel is used in Real-World Data Analysis

Microsoft Excel is a powerful tool used across the world typically in organizing and visualizing data. While most people use it for simple tasks such as creating graphs and tables with scanty knowledge in graphs, Excel can do much more and this explains why almost around 70% of companies solely rely on it to run their businesses.

Excel is widely used for examining and analyzing data in different industries. In the business world, companies rely on Excel to predict their sales, measure their progress, and manage all their inventory. The application allows managers to see patterns and trends more easily, enabling them to make sound decisions from it. In finance, Excel allows professional practitioners to prepare both income statements and balance sheets, as well as budgeting documents. Financial analysts rely on Excel to carry out calculations and compare the results over different time frames. Marketing teams, on the other hand, use Excel to keep track of campaign results, examine how customers behave, and represent their ROI using graphical tools and pivot tables.

There are many formulas and features that I have learned in Excel, but the ones that stand out include VLOOKUP, pivot tables, and creating dashboards. VLOOKUP allows us to search for a value in one column and return another value of interest from another column within the same row. This enables us to find an attribute we are interested in from what we currently have without having to scroll through large datasets. Pivot tables are particularly important, especially in reporting. They allow us to summarize data in a form that is easy to interpret or gain insights at a glance. Pivot tables enable us to condense information by dragging and dropping instead of writing lengthy formulas and code. From the summaries we get from pivot tables, we can generate all forms of graphs and pie charts, which we can use to create dynamic dashboards that tell a story. These dashboards, if well created, can assist in analyzing trends and making decisions. Dashboards tell stories without having to look at what is happening in the background, which is useful, especially for executives.

Personally, I have witnessed the power of Excel as a data analysis tool. I now understand that data allows us to tell a complex story in an interesting yet useful way. We live in an AI-driven age where data is increasingly becoming important in training models. Our ability to present it in an unbiased way can lead to the development of accurate models useful in day-to-day activities. Data is not just numbers; it is about finding answers to important questions and making sound decisions that impact lives.
