1. Spreadsheets Lesson 3: Formatting and formulas

2. Lesson Objectives To understand how to format a spreadsheet to improve the appearance To understand more complex formulas to find the average, minimum and maximum totals

3. Formulas Which formulas do we already know? Why do we use these formulas? Go to Common K>ICT>Year 7>Spreadsheets Open the file called Games

4. Average How would you work out the average of these numbers? Average = sum of elements/number of elements Average = (7+8+5+9+10+10+9+8)/8 Score 7 8 5 9 10 9 8

5. Games You need to fill in the income column (From F5 to F14) When you have worked out individual totals, use a formula to fill in the TOTAL INCOME cell

7. Average In excel we can make this process a lot easier. =AVERAGE(A1:A9) All formulas start with an = The name of the formula is AVERAGE The range of cells that we want to find the average for is A1 to A9

8. Max and Min You can work out the maximum number and the minimum number in the same way. =MAX(A1:A9) =MIN(A1:A9) Fill in the Average, Min and Max cells on your sheet
