Hands-On Data Collection

Measure your height in inches Record your measurement Place a sticky dot on our class chart Create a dot plot together

Understanding Our Data

Measures of Center and Variability

Mean: Add all heights ÷ 25 students Median: Middle value when ordered Range: Tallest height - Shortest height These help us understand our data better

Create Your Own Statistical Questions

Work in groups of 5 Brainstorm 2-3 statistical questions Think about our class or school Remember: expect different answers!

Key Takeaways

Statistical questions expect variability in answers Data can be organized using dot plots Mean, median, and range help us understand data patterns Collecting and analyzing data helps us learn about our world
