Advanced Probability: Uncertainty in Data

Examines multiple variables at the same time to assess how different factors interact

Example: a retail company considers three possible economic conditions to forecast next year's sales

Focuses on the effect of changing one key variable while keeping others constant

Often used for risk assessment to determine the most influential variables on an outcome

Example: a tech company tests how changes in advertising budget impact website traffic
