📚 Quick Study Guide

  • 🔢 Mean: The average of a set of numbers. Calculated by adding all the numbers and dividing by the count of numbers. Formula: $\text{Mean} = \frac{\text{Sum of numbers}}{\text{Number of numbers}}$
  • 📊 Median: The middle value in a sorted list of numbers. If there's an even number of values, it's the average of the two middle numbers.
  • Mode: The value that appears most frequently in a dataset. A dataset can have no mode, one mode, or multiple modes.
  • 📈 Range: The difference between the largest and smallest values in a dataset. Formula: $\text{Range} = \text{Largest Value} - \text{Smallest Value}$
