Excel Formulas Every Data Analyst Should Know
This topic becomes much easier when we connect the concept to a real business problem instead of memorizing definitions.
Chapter Overview
Formulas are the working tools of Excel analysis. They help us calculate totals, assign labels, fetch values, and prepare metrics for reports.
Useful Functions
Common functions include SUM, AVERAGE, COUNTIF, IF, TEXT, LEFT, RIGHT, XLOOKUP, and IFERROR. Students should focus on understanding why a formula is used, not only how to type it.
Excel Example
=IF(E2>=5000,"High Value","Standard")
=XLOOKUP(A2,Customers!A:A,Customers!C:C,"Not Found")
=COUNTIF(B:B,"Delhi")Learning Advice
Build formulas on small samples first. Once the result looks right, apply it to the full column. This reduces confusion and makes debugging easier.
