Questions and Answers

Which approach is described for creating models?

  • Induce, Deduce, Infer
  • Observe, Draw, Predict
  • Analyze, Interpret, Conclude
  • Collect Data, Test Predictions, Revise (correct)

    • What is the purpose of models in the context of human performance?

  • To confuse observations
  • To generalize without evidence
  • To overfit the data
  • To isolate components for closer examination (correct)

    • Why are models of human performance described as an inductive process?

  • Because they involve drawing specific conclusions from broad observations
  • Because they rely on deductive reasoning
  • Because they are based on overfitting data
  • Because they start from specific observations to form broader generalizations (correct)
