1. 8.4 Modelling and Presenting Numeric Data Introduction to Spreadsheets

2. Learning Objectives Pupils should be able to identify the main features of a spreadsheet including formatting and simple formula Pupils should be able to recognise the potential capabilities of spreadsheets

3. Lesson Outcomes Pupils should be able to correctly identify the features of a spreadsheet Pupils should be able to use formula correctly

4. Spreadsheet Features Column Row Cell Reference Cell AutosumChart wizard Sort

5. Formatting Cells We can format cells so that information is easier to interpret Spreadsheets allow us to: Add colour Change the alignment (e.g. centre) Add emphasis (e.g. bold, italic) Change the font and size of text Change the data type (e.g. currency, number)

6. Using Simple Formulae Spreadsheets allow us to calculate information quickly We use a formula so that if information changes, our calculations also change automatically Formulae always begin with an equals sign (=)

7. Using Simple Formulae To calculate the cost of buying each item once we would: In cell B3 we need to write a formula that will include all of the data in column B =(b2+b3+b4+b5+b6+b7)

8. Simple Formula CommandKey Multiply* Divide/ Subtract- Addition+

9. Simple Functions Some spreadsheets have some pre-defined functions to make calculating data easier: Function SumAdds together a range of numbers AverageCalculates the average of a range of numbers MaxFinds the highest number MinFinds the lowest number

10. Functions =sum(b2:b7) A dialogue box will appear to guide you with the function values This functions adds all of the values between b2 and b7
