Data Analysis and Probability

Making Sense of Information

Data analysis is all about collecting, organizing, and interpreting numbers. Probability helps you predict how likely something is to happen.

Data Analysis

  • Mean: The average of a set of numbers.
  • Median: The middle value when numbers are in order.
  • Mode: The number that appears most often.

Probability

Probability is the chance that something will happen, measured as a number between 0 (impossible) and 1 (certain).

Probability Formula

\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

Real-World Examples

Data and probability are key for making decisions—like predicting the weather, or figuring out your chances of winning a game.

Examples

  • Rolling a 3 on a six-sided die: \( \frac{1}{6} \) chance

  • Finding the mean score of 80, 85, and 95: \( \frac{80+85+95}{3} = 86.67 \)

In a Nutshell

Data analysis and probability help you understand and predict outcomes.
