Multiple choice

Which decision-making method involves using a matrix to evaluate options based on multiple criteria?

  1. Nominal group technique

  2. Weighted voting

  3. Multi-criteria decision analysis

  4. Condorcet method
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Multi-criteria decision analysis (MCDA) is a decision-making method that involves evaluating options based on multiple criteria. A matrix is used to compare the options against each criterion, and weights are assigned to reflect the relative importance of each criterion. The option with the highest overall score is selected as the winner.

Multiple choice

Which decision-making method involves using a series of pairwise comparisons to determine the most preferred option?

  1. Weighted voting

  2. Condorcet method

  3. Multi-voting

  4. Pairwise comparison
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pairwise comparison is a decision-making method where participants compare each option to every other option, one pair at a time. They indicate which option they prefer in each pair, and the option with the most wins is selected as the winner. This method is particularly useful when there are a large number of options and it is difficult to evaluate them all simultaneously.

Multiple choice

Which decision-making method involves using a mathematical formula to calculate the best option?

  1. Multi-criteria decision analysis

  2. Weighted voting

  3. Condorcet method

  4. Simple additive weighting
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Simple additive weighting (SAW) is a decision-making method that involves using a mathematical formula to calculate the best option. Each option is evaluated based on multiple criteria, and a weight is assigned to each criterion to reflect its relative importance. The option with the highest overall score is selected as the winner.
