What you need to know
Answer each one before you reveal it.
What comparison do decision trees allow, what do they leave out, and what limits how far they can be trusted?
Find the net gain on an expected value of 330,000 less a cost of 170,000, and which way do you work at each stage?
What type of comparison do decision trees enable between strategic options?
What does a square symbol represent in a decision tree?
Give examples of qualitative factors that decision trees do not account for.

Expected value vs Net gain
Expected value: the total of each outcome multiplied by its probability. Net gain: the figure left once the initial investment is subtracted.
Questions from this topic
Each one with the model answer underneath.
- 1
What does a square symbol represent in a decision tree?
Model answer
A decision node, which represents a point where a choice must be made between alternative courses of action.
- 2
What does a circle symbol represent in a decision tree?
Model answer
A chance node, which represents a point where different outcomes may occur, each with an associated probability.
- 3
What must the probabilities at each chance node sum to?
Model answer
1 (or 100%).
- 4
When calculating expected value at a chance node, what must first be identified?
Model answer
Each possible outcome and its financial value.
- 5
After identifying outcomes and their values, what is the next step in calculating expected value?
Model answer
Multiply each outcome value by its probability.
- 6
What is the final step in calculating expected value at a chance node?
Model answer
Sum all the probability-weighted values.

Decision Tree Analysis revision questions
- What does Decision Tree Analysis cover in CCEA A-Level Business?
- 2 subtopics: drawing a decision tree and calculating expected value and the uses and limitations of decision tree analysis. Each one has its own page with questions and model answers.
- How is Decision Tree Analysis organised?
- By the CCEA 3210 specification, subtopic by subtopic, so it matches the order you are taught it in.
