Part |1: |Excel |in |OM |- |ANS |-N/a
What |is |a |model? |- |ANS |-A |purposeful |representation |of |key |elements |of |objects |or |systems |
and |the |relationships |among |them; |provides |abstract |representation |of |something |real
What |should |be |omitted |in |a |model? |- |ANS |-Useless |data
What |are |the |four |different |types |of |models? |- |ANS |-1. |Mental |Models
2. |Visual |Models
3. |Physical |Models
4. |Mathematical |Models
What |is |mental |model? |- |ANS |-Models |that |tell |you |what |to |do; |example: |traffic |light, |ski |slope
|difficulty |indicator
What |is |a |visual |model? |- |ANS |-Graphic |model; |example: |maps |and |flowcharts
What |is |a |physical |model? |- |ANS |-A |3D |representation, |usually |intended |for |larger |objects |to |
scale; |example: |model |of |a |cruise |ship
, What |is |mathematical |model? |- |ANS |-Model |that |shows |a |quantitative |representation |of |a |real
|problem. |This |is |really |the |only |model |that |we |will |be |using; |example: |weather |forecasts, |
spreadsheet, |balance |sheet |etc.
What |are |the |two |types |of |mathematical |models? |- |ANS |-1. |Algebraic: |Equations |that |
represent |relationships |between |quantities |in |a |system
2. |Spreadsheet: |Way |of |implementing |mathematical |models; |usually |more |visually |appealing
What |are |the |ABCs |of |spreadsheet |modeling? |- |ANS |-A |- |All |work |must
B |- |Be:
C |- |Correct |- |Correct |Numerical |Answers
D |- |Documented |- |Descriptive |Labels, |Comments, |Formatting
E |- |Engineered |- |Design |is |important; |draw |on |paper |first
F |- |Flexible |- |Accurate |results |if |input |changes; |formulas |
contain |cell |references |and |NOT |hard |coded |numerical |values
What |is |an |Influence |Chart? |- |ANS |-A |simple |diagram |to |show |the |relationships |between |
inputs |and |outputs |in |a |spreadsheet |model; |typically |a |simple |hand-drawn |model
Why |do |we |use |influence |charts? |- |ANS |-To |define |the |problem |structure, |ignore |all |numerical |
data, |identify |the |main |elements |of |the |model, |and |define |the |assumptions |of |the |model
