Answer Key

Wisdom: using information to decide

Section A: Quick Questions

A — Using information and experience to make a good decision

B — Wisdom

A — Data, information, knowledge, wisdom

A — The numbers 31, 24, 19 in a list

B — The same information can lead to different good decisions in different situations

Section B: Match the Pairs

Wisdom → Using information and experience to make a good decision

Data -> Information -> Wisdom → The path from raw facts, to facts with meaning, to a good decision

Wisdom turns information into a decision by applying experience → Information: Rain is forecast at 3 pm Wisdom: Move the footy training to the gym

Wisdom needs context, so the same information can lead to different decisions → Info: Battery is at 10% Wisdom at home: Charge it later Wisdom on a hike: Turn on power saving

Data: 38 C Wisdom: 38 C → The raw number is only data. Repeating it is not wisdom because no decision is made.

Wisdom = Data + Data + Data → Collecting more data does not create wisdom. Wisdom comes from applying information and experience.

Section C: Definitions

Wisdom — Wisdom is using information and experience to make good decisions. It is the top step of the DIKW pyramid, above data and information, and it needs context to work.

Section D: Fill in the Blanks

data ← 38
information ← "Today is hot"
wisdom ← "Wear a hat at lunch"

data → information → wisdom

wisdom ← decide(information, context)

data ← 38
information ← "Today is hot"
wisdom ← "Wear a hat at lunch"

if rain_chance > 70 then
  wisdom ← "Take an umbrella"
end if

Section E: Spot the Error

C — The variable was created as info, not infos. Printing an undefined variable fails. It should be print info.

B — An if statement needs the keyword then after its condition. Using the information (score < 50) to make a decision is wisdom. The line should be if score < 50 then.

C — The decision is backwards. Ordering more stock only makes sense when sales are above target, so the condition should be sales > target.

A — Assignment puts the value into the variable, so the variable goes on the left. The raw data should be stored with rainfall <- 12.

C — The 'greater than or equal to' operator is written >=, not =>. The line should be if mark >= passMark then.
