A Day in the Life
What your typical workday looks like
Imagine starting your day by looking at a massive amount of information – maybe customer reviews, sales numbers, or website activity. You’ll spend time cleaning this data, making sure it’s accurate and ready for analysis. Then, you might build a model using programming to predict what customers might buy next or why a certain product is popular. You’ll also create charts and reports to explain your findings to people who aren’t data experts, helping them understand the story the data is telling and make important business decisions.
