Data Analysis and Probability

Understanding Data

Data analysis is collecting, organizing, and interpreting information to make smart decisions.

Reading Graphs and Charts

Bar graphs, line graphs, and pie charts show data visually. Look for patterns, differences, or trends.

Mean, Median, and Mode

  • Mean: The average.
  • Median: The middle number when data is in order.
  • Mode: The number that appears most.

Probability

Probability tells how likely something is to happen, using numbers from 0 (impossible) to 1 (certain).

Why It Matters

Data and probability are used in sports stats, weather forecasts, and games of chance!

Examples

  • Rolling a dice and getting a 6 has a probability of \( \frac{1}{6} \).

  • Finding the mean test score for five students: add and divide by 5.

In a Nutshell

Data analysis and probability help us predict and understand real-life situations.
