Your Mission

What You'll Do Today

The Full Data Cycle — Start to Finish

Choose a question YOU want to investigate
Collect data from classmates using tally marks
Organize your data into a frequency table
Draw a bar chart or pictograph
Share what the data says — 1 observation + 1 inference
This is exactly what real data scientists do. Every. Single. Time.
Phase 1 · 15 min

✍️ Phase 1: Plan Your Project

Write your question
It must be fair and data-answerable
It needs 3–5 specific answer choices
Ask: "Could I count the answers?"
Good examples:
"What is your favorite season?"
"How do you get to school?"
"What is your favorite subject?"
Plan your collection
Who will you ask? (your sample)
How many people? (aim for 10+)
Method: survey, observation, or measurement?
How will you record? (tally marks!)
✅ Check: Is your question fair? Is it specific? Is it answerable with data?
Phase 2 · 15 min

📋 Phase 2: Collect Your Data

Survey Time!

Get your clipboard and tally recording sheet
Ask at least 10 classmates your question
Read the question exactly as written — no changes!
Record each answer as a tally mark immediately
Each person gets asked only once
Remember the survey rules from Session 3:
Ask exactly as written
Give the choices — don't suggest one
Record immediately
Each person once only
Say "thank you!"
Phase 3a · part of 10 min

🗂️ Phase 3: Organize — Frequency Table

Transfer your tally marks into a clean frequency table. Remember: 3 columns — Category · Tally · Frequency — and a Total row at the bottom.
Quick self-check before moving to the chart:
  • All categories are listed in the left column
  • Tally marks are copied from my recording sheet
  • Frequency numbers are correct
  • Total row is filled in
  • Total matches how many people I asked
Phase 3b · part of 10 min

📊 Phase 3: Visualize — Draw Your Chart

Bar chart checklist
  • Title at the top
  • Category labels on one axis
  • Even number scale starting at 0
  • Each bar = correct height
  • Color used
Pictograph checklist
  • Title at the top
  • Category labels on the left
  • Key explains what 1 symbol = how many
  • Correct number of symbols per row
  • All symbols same size
Phase 4 · 7 min

🎤 Phase 4: Present Your Findings

You have 60–90 seconds. Use this structure to guide what you say:
1."My question was: _______________"
2."I asked ___ people using _______________" (method)
3.[Show chart] "My chart shows that _______________" (observation)
4."This might mean that _______________" (inference)
5."If I could do this again, I would _______________" (reflection)
You've got this. You've done every one of these steps already — this is just putting it all together!

Connecting to the World

Data Science Is Everywhere

🏥 Health
Doctors collect data on patients to find what treatments work
Scientists track disease to keep communities safe
🌍 Environment
Scientists measure temperature data over decades to track climate change
Wildlife trackers count animals to protect endangered species
🎮 Technology
Apps collect data on what features you use to make them better
Video games use data to balance difficulty
The skills you learned this course — asking good questions, collecting fairly, visualizing honestly, reading critically — are real data science skills.
Reflection

One Last Reflection

"The most important thing I learned about data is ___."
Possible answers — all valid!
"You have to ask fair questions"
"Charts can trick you"
"Data helps you make better decisions"
"You need enough people in your sample"
"Organizing messy data takes real skill"
Also think about:
What was the hardest part of the whole course?
What surprised you most?
What would you teach someone else first?
What question would you investigate next?
