❓ Frequently Asked Questions
What is a pivot table and when should you use it?
A pivot table summarizes large data by categories (e.g., by month, product). It lets you drag fields to quickly compute sums, averages, counts, and more without altering the source data.
How do you create a simple sum formula in Excel?
Use the SUM function, e.g., =SUM(B2:B100). It adds all numbers in the range; use AutoFill to apply to other rows/columns.
What is the purpose of charts in Excel?
Charts convert numbers into visuals (bar, line, pie) to reveal trends, comparisons, and outliers at a glance.
How can you identify trends and patterns in a dataset using Excel?
Use a line chart to view changes over time, add a trendline for direction, and apply conditional formatting to highlight high/low values.
