Data validation in a spreadsheet model

Spreadsheets

Unit Summary

In this unit pupils will explore how to use spreadsheets to store and manipulate data. They will use common functions and extract data to create visual representations using charts. Pupils will use spreadsheets to track and calculate income, make predictions, and answer "what if…?" questions.

Lesson Summary

You will learn to apply data validation techniques to improve data accuracy.

Key Notes

  • Data validation is a tool in spreadsheets that controls what kind of data can be entered into a cell.
  • It is used to help prevent mistakes, such as typing the wrong word or entering numbers outside a set range.
  • Various types of criteria can be used in data validation, such as text, dates and number ranges.
  • Data validation can show helpful messages when users make an error.
  • Using data validation helps keep data accurate and consistent.

Vocabulary To Learn

  • data validation: a tool that controls what kind of data can be entered into a cell
  • citeria: the rules set in data validation that decide what data is allowed in a cell
