Q: How to explain your job to a child?
A: An analytics job is like being a detective! Analysts use data - which are facts and numbers about things - to understand stuff and answer questions. For example, if a company wanted to know what ice cream flavors kids like best, an analyst would look at data about ice cream sales to figure it out. They would look for patterns and clues in the data that could help solve the mystery of which flavors are most popular
