 [ ] datum [ ] label [ ] output [ ] result
3. A cell contains a number or date. This is called a .......
 [ ] input [ ] numeric [ ] output [ ] value
4. A formula is not normally displayed in a cell. It is found .......
 [ ] in the address bar [ ] in the formula bar [ ] in the formulae bar [ ] in the rule bar
5. Functions are pre-programmed formulae which .......
 [ ] have to be learned by heart [ ] perform tasks a user could not create a formula to do [ ] save the user having to type in regularly used formulae [ ] work better than formulae created by a user
6. Which of these is not a commonly used function?
 [ ] MAX [ ] MIN [ ] MINGIN [ ] MOD
7. Which is not an advantage of using models?
 [ ] Is cheaper than doing the real thing, e.g. car crashes [ ] Models usually give only approximate answers [ ] They can be used for making predictions [ ] Training people to do dangerous jobs without any risk
8. Why are computer models sometimes unreliable?
 [ ] Real life often has unpredictable events occur [ ] The models might be processing too much information [ ] The rules were probably entered incorrectly [ ] They have been run on old computers
9. A spreadsheet model might be tested by .......
 [ ] changing the input data and looking at the predictions [ ] changing the rules used and looking at the predictions [ ] comparing the model predictions with real life results [ ] It is a computer model and doesn't need testing
 [ ] You can change input values and check the results [ ] You can change the rules and check the results [ ] You can change the rules and data and check the results [ ] None of the above will work Computer Science: Middle School: Grades 6, 7 and 8 Quiz - Models 3 (Answers)

 [ ] have to be learned by heart [ ] perform tasks a user could not create a formula to do [x] save the user having to type in regularly used formulae [ ] work better than formulae created by a user
They save the user time and unnecessary effort
6. Which of these is not a commonly used function?
 [ ] MAX [ ] MIN [x] MINGIN [ ] MOD
A huge number of helpful functions are available
7. Which is not an advantage of using models?
 [ ] Is cheaper than doing the real thing, e.g. car crashes [x] Models usually give only approximate answers [ ] They can be used for making predictions [ ] Training people to do dangerous jobs without any risk
Computer models are not always very reliable
8. Why are computer models sometimes unreliable?
 [x] Real life often has unpredictable events occur [ ] The models might be processing too much information [ ] The rules were probably entered incorrectly [ ] They have been run on old computers
Unpredictable events may not be covered by the rules
9. A spreadsheet model might be tested by .......
 [ ] changing the input data and looking at the predictions [ ] changing the rules used and looking at the predictions [x] comparing the model predictions with real life results [ ] It is a computer model and doesn't need testing
