Mrs Wallace is a department head in a high school, and is looking at the performance grades for all students in one semester. What features can she use in Google Sheets to help analyze the data efficiently without having to search through it manually?

Filters in Google Sheets narrow visible rows so patterns in grade data can be reviewed without manually scanning every entry. Filter views can also preserve different analysis views without changing the underlying spreadsheet for others. Charts convert spreadsheet values into visual summaries that make progress, comparisons, and trends easier to interpret. These features support efficient data analysis while keeping the original data in one organized sheet.
