In a nutshell: Analyze data and use probability to predict outcomes.
## 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.
\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.
Key terms
- Mean
- The sum of values divided by how many there are.
- Probability
