Utajifunza

  • Formulate linear, quadratic and exponential models from situations and data.
  • Interpret the parameters of a model and use it to make predictions with stated assumptions.
  • Validate a model against data and explain where and why it fails.

Fasili

  • A mathematical model is a simplified mathematical description of a real situation, together with its assumptions.
  • Validation compares a model's predictions with observations.

Nadharia

  • A quantity growing continuously at rate r doubles every (ln 2)/r units of time.
  • Every model leaves out features of reality; it is judged by whether it serves its purpose.
  • Extrapolating far beyond the range of the data is risky.

Mawazo potofu ya kawaida

  • Treating a model's output as fact rather than as a consequence of its assumptions.
  • Choosing the model that best fits past data regardless of whether it is plausible.
