Experienced data scientists Piyanka Jain and Puneet Sharma offer an exceptionally clear, illustrated guide to data analysis, including meaningful, real case studies and actionable best practices.

They say that non-analysts, like managers and marketers, can learn powerful analytical tools easily and conduct their own analyses without a professional analyst or data scientist.
