Data, Statistics, and Probability

Gathering and Understanding Data

Data is information—like survey results or test scores. Statistics helps you organize, analyze, and make sense of data.

  • Mean: The average.
  • Median: The middle value.
  • Mode: The most frequent value.

Working with Probability

Probability helps you predict how likely something is to happen. It’s measured from 0 (impossible) to 1 (certain).

\( \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \)

Real-Life Uses

Statistics and probability help you decide which movie to watch, make predictions in sports, and understand news reports.

Key Formula

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

Examples

  • Calculating the average score of your basketball games.

  • Predicting the chances of rolling a 6 on a die.

In a Nutshell

Analyze data and use probability to predict outcomes.

Key Terms

Mean
The sum of values divided by how many there are.
Probability
How likely an event is to happen.
