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 >ICT>Year 7>Spreadsheets
Open the file called Games

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

6. 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

7. 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

8. Formatting
Formatting is when you use presentation tools to make something look more presentable.
Which tools would you use to make the spreadsheet more presentable?

9. Borders and shading
At the top of your page you have options to add a border.
Select the cells you want to alter, then select the border you want to use.
You can fill with the paint bucket and change the font colour too

10. Merge and Wrap
If you want to merge some cells together, so that they become one big cell you need to
Highlight the cells. Click MERGE AND CETNRE at the top.
You might also want to wrap text. This puts the text onto more than one line

11. Data Type
You should have noticed that the costs in spreadsheet do not have £ signs.
Alter the type of data in the cell by highlighting all the ones that need changing
Right click and select Format Cells
Select the Currency type.
