Study Notes

Forecasting in Marketing

  • Forecasting is important in marketing departments to predict future trends and make informed decisions.

Forecasting Techniques

  • Forecasters primarily use historical data to predict the future.
  • The primary reason for using forecasting in real-world systems is to make informed decisions and minimize uncertainty.

Forecasting in Education

  • School boards need to forecast an increase in the number of school-going children to plan for infrastructure and resource allocation.

Basic Strategy in Forecasting

  • The basic strategy employed in most forecasting techniques is to use historical data to make predictions about future events.

Limitations of Experimentation

  • It is impractical or impossible to experiment directly with a real-world system in some cases because it can be expensive, dangerous, or unethical.

Ali's TV Purchase Options

  • Ali has two options for purchasing a TV: paying cash upfront or taking a loan from a financial society with an interest rate of 12%.

Importance of Mathematical Modeling

  • Mathematical modeling is important because it allows experts to analyze and understand complex real-world systems.
  • Experts from different fields work together in mathematical modeling to develop a comprehensive understanding of a system.
  • During the process of building a mathematical model, factors such as assumptions, variables, and relationships are revealed.
  • Having a mathematical model helps in understanding a real-world system by providing a simplified representation that can be analyzed and used for prediction and decision-making.
