Create and interpret various types of graphs and charts using weather data scenarios!
Scenario: You're helping the school weather station track temperature data for one week. The daily high temperatures were: Monday (72°F), Tuesday (75°F), Wednesday (78°F), Thursday (80°F), Friday (82°F), Saturday (85°F), Sunday (83°F). How can you display this data using different types of graphs?
Graphs are visual ways to show data. They help us see patterns, compare numbers, and understand information quickly. Different types of graphs are best for different kinds of data.
Graphs = Visual + Data + Patterns
Pictures that help us understand numbers
Make data easier to understand, show patterns clearly, compare different values
Weather charts, sports statistics, school test scores, sales reports
Bar graphs use bars (rectangles) of different heights to show and compare data. They're great for comparing different categories or groups.
Weekly High Temperatures
Best for: Comparing different categories, showing exact values
Line graphs use points connected by lines to show how data changes over time. They're perfect for showing trends and patterns.
Temperature Trend Over Week
Best for: Showing changes over time, identifying trends and patterns
Pie charts use slices of a circle to show parts of a whole. Each slice represents a portion of the total data, and the size of the slice shows how much of the total it represents.
Temperature Categories
Best for: Showing parts of a whole, comparing proportions
A basketball team's scores for 5 games were: Game 1 (85), Game 2 (92), Game 3 (78), Game 4 (95), Game 5 (88). Which type of graph would best show how the team's performance changed over time?
Answer: Line Graph
Because we want to show changes over time (from Game 1 to Game 5)
A survey of 100 students showed: Vanilla (30), Chocolate (40), Strawberry (20), Mint (10). Which type of graph would best show the proportion of each flavor?
Answer: Pie Chart
Because we want to show parts of a whole (100 students)
