In a nutshell: Learn to interpret data and calculate the chances of different events.
## Understanding Data
Data analysis is about collecting and interpreting information. You'll learn to read charts, graphs, and tables.
## Measures of Central Tendency
- **Mean:** The average (\( \text{Mean} = \frac{\text{Sum of values}}{\text{Number of values}} \))
- **Median:** The middle value when data is ordered.
- **Mode:** The value that appears most often.
## Introduction to Probability
Probability measures how likely something is to happen. It's calculated as:
\[
\text{Probability} = \frac{\text{Number of successful outcomes}}{\text{Total number of outcomes}}
\]
## Real-World Use
Data and probability are found in weather forecasts, sports statistics, and games of chance!
Examples
- What is the median of 2, 4, 7, 10, 12?
- If you roll a fair die, what is the probability of getting a 5?
