#Data Interpretation: Tables and Graphs 📊

#Types and Components of Graphs

• Tables and graphs are your visual allies for understanding data. Think of them as maps that guide you through the numbers.
• Common graph types:
  • Line graphs: Show trends over time. Think stock prices or temperature changes.
  • Bar graphs: Compare categories. Like the number of students in different clubs.
  • Histograms: Display frequency distributions. How many students scored in each grade range.
  • Scatterplots: Reveal relationships between two variables. For example, study time vs. test scores.
  • Box plots: Summarize data distribution using the median, quartiles, and range.
• Key components:
  • Title: What's the graph about?
  • Axes labels: What do the x and y axes represent?
  • Scales: How are the numbers spaced?
  • Data points: The actual data being shown.
  • Legend: What do different colors or symbols mean?
  • Footnotes: Any extra info or context.

• Patterns: Notice clusters, gaps, or outliers. Are there any surprises?
• Relationships:
  • Positive correlation: Both variables increase together. (e.g., study hours and grades) 📈
  • Negative correlation: One variable increases as the other decreases. (e.g., temperature and hot chocolate sales) 📉 ...
