2. SPREADSHEETS USED IN THE REAL WORLD Spreadsheets are used by many organisations, in various of different ways all depending on the type of business. Some examples spreadsheets are used for are records of students exam results, assessment grades. The reason why businesses use spreadsheets is because they obtain special features and tools that are available. For example, formula to perform much more complex and complicated calculations that a human wouldn’t be able to do very quickly. This would certainly be a benefit for businesses such as accounting. Also spreadsheets are useful for exam results because spreadsheets can hold largeamounts of data in one file.

3. EXAMPLES OF TWO ACTIVITIES GROCERY SPREADHSEET TOOLS AND FEATURESACCOUTING SPREADHSEET TOOLS AND FEATURES

4. GROCERY ACTIVITY USING A SPREADSHEET FOR A GROCERY STORE IS VERY USEFUL BECAUSE IT WILL PRODUCE CALCULATION AUTOMATICALLY. FOR EXAMPLE IF YOU WAS TO CHANGE THE PRICE OF THE POTATOES, THE SALES WOULD AUTOMATICALLY BE CALCULATED FOR YOU. ALSO THIS SPREADSHEET USES HLOOKUP. THIS SEARCHES VALUES IN THE SPREADSHEET ROWS. e.g. (lookup_value, table_array, row_index_num, [range_lookup])

5. ACCOUNTING ACTIVITY USING SPREADSHEETS FOR ACCONTING IS DIFFERENT TO GROCERY STORE. THIS SPREADSHEET USES VLOOKUP, THIS MEANS THAT ALL THE DATA IS VERTICALL UNDER THE HEADINGS. TO SEARCH A VALUE IN THE FIRST COLUMN OF A TABLE AND THEN RETURNS THE VALUE FROM ANOTHER DIFFERENT TABLE e.g. (lookup_value,table_array,col_index_num,range_lookup)

6. FEATURES USED WITHIN A SPREADHSEET - Formulae’s are used in spreadsheets so that when a piece of data is changed, the formulae would make sure that the piece of data changed is updated all the way throughout the spreadsheet where necessary. - Accountants could use graphs and charts allow to present the data in a visual and much more exciting form. IF statements can be used to highlight a certain cell group and give them their particular value. Hyperlinks can also be used to locate you to another page within that spreadsheet. Tools: -VLOOKUP/HLOOKUP (Vertical Lookup) & (Horizontal Lookup) -(=SUM) -IF

7. Grocery store Spreadsheets allow large supermarket chains to store high volumes in data in one spreadsheet. Also spreadsheets allow you to do automatic calculations when necessary, for example when price of groceries change it will automatically be updated onto their spreadsheet. This therefore allows users and businesses to enter any mathematical formulas ranging from simple calculations to complex statistics which aren’t as easy to work out mentally. To perform a calculation from different cells on a spreadsheet you have to press a mathematical symbol on the keyboard, for example ‘+’ sign, then click the second cell. This is an advantage to humans as it takes less time to perform complicated sums. In accounting spreadsheets, the usability allows the user to analyse data in simple ways just by creating borders. Most spreadsheets that people have can create graphs, pie charts and bar charts. This is used to improves visual learning and improves the way the spreadsheet is presented and much easier to understand. IMPROVING PRODUCTIVITY & USABILITY

8. ADVANTAGES - What “IF” sum, allows complicated calculation to be worked out via spreadsheets. -Information can be presented in an organised way for example A1:A10 and E1:E10. -Insert borders, bold titles and headers to make tables clearer and easier to understand. -Align data to the Right, Centre, or far left. -Format the cells to represent what the numbers mean i.e. currency. -Share the data between different people within the business. -Saves time and much cheaper than printing out paper. -Produce graphs to represent information visually.

9. DISADVANTAGES -Spreadsheets aren’t as secure as databases -Cannot create reports or queries in a spreadsheet. -Spreadsheets wont check validity of the data that is inserted into the spreadsheet. -Equipment and software can be very expensive to buy. -Staff within the business would need to be trained on how to use the software and equipment.
