Tricky because 'technical stakeholder' is vague.
Start by clarifying the stakeholder's technical background and what decision they need to make with the model. Then explain linear regression using an intuitive analogy, followed by a concise technical definition, and tie it back to how it helps solve their problem. Emphasize the assumptions and limitations to set realistic expectations.
Pro tip: Use a concrete example relevant to the stakeholder's domain (e.g., ad spend vs. conversions) to make the concept tangible, and always connect the explanation to the business value or decision it enables.
Ask about their technical background and what they aim to achieve with the model. This tailors your explanation to their needs and avoids unnecessary jargon.
Explain linear regression as drawing the best-fitting straight line through data points to predict an outcome, like predicting house prices based on size.
Define it as a statistical method that models the relationship between a dependent variable and one or more independent variables by minimizing the sum of squared errors.
Mention key assumptions like linearity, independence, and homoscedasticity, and note that it may not capture complex non-linear relationships.
Explain how the model's predictions or insights can inform decisions, such as optimizing marketing spend or forecasting sales.
