📊 Part 1: Understanding Variables for Scatter Plots

Answer: Hours of study time and test scores. This pair is numerical and likely to show a correlation.

Answer: One categorical and one numerical. This allows for a meaningful scatter plot.

Answer: Good questions include: "How does shoe size relate to height?" and "How does time spent exercising affect heart rate?" These involve numerical data.

Variable 1 (x-axis): Hours of sleep

Variable 2 (y-axis): Grades

Answer: Variable 1 is hours of sleep, and Variable 2 is grades.

✏️ Part 2: Creating Your Own Data Questions

Your question: ________________________________________________________________

Variable 1: _____________________________ Variable 2: _____________________________

Example: "How does height relate to weight?" Variable 1: Height, Variable 2: Weight.

Example: "How does the number of hours spent studying affect test scores?"

Answer: The x-axis would represent hours of video games played, and the y-axis would represent hours of sleep. Each point on the plot would show the relationship between these two variables.

Question 1: ________________________________________________________________

Question 2: ________________________________________________________________

Example: Question 1: "How many days did you attend class?" Question 2: "What was your final exam score?"

🎯 Part 3: Data Analysis Planning

Answer: Collect data on the number of books read by each student and their corresponding reading test scores. Use a survey to gather this information.

My chosen topic: _________________________________

My data question: ________________________________________________________________

This would create a scatter plot with _________________ on the x-axis and _________________ on the y-axis.

Example: Chosen topic: Technology use and grades. Data question: "How does time spent on homework relate to grades?" X-axis: Time spent on homework, Y-axis: Grades.

🔑 Answer Key

1. Best relationship: Hours of study time and test scores.

2. Both variables must be one categorical and one numerical.

3. Good scatter plot questions: "How does shoe size relate to height?" and "How does time spent exercising affect heart rate?"

4. Variables: Hours of sleep (x-axis), Grades (y-axis).

5. Example question: "How does height relate to weight?"

6. Example question: "How does the number of hours spent studying affect test scores?"

7. Data representation: X-axis for hours of video games, Y-axis for hours of sleep.

8. Example questions: "How many days did you attend class?" and "What was your final exam score?"

9. Data collection plan: Survey students on books read and test scores.

10. Example topic: Technology use and grades. Data question: "How does time spent on homework relate to grades?"
