Understanding Uncertainty and Trends

Statistics and probability help you make sense of uncertainty and data trends, both on the GMAT and in business.

Core Concepts

• Measures of central tendency (mean, median, mode)
• Probability rules (independent and dependent events)
• Counting principles (permutations and combinations)
• Interpreting standard deviation

Problem-Solving Tips

• Use probability formulas to calculate chances of events
• Apply counting methods for arrangements and selections
• Analyze data sets for variability and outliers

These skills are essential for making predictions and informed decisions.
