Mini Lesson

Have you ever wondered what your family's favorite things are? A survey is a way to ask people questions and collect their answers so you can learn from the data!

Step 1 — Write your survey question

  • Choose a topic you are curious about.
  • Write a clear question with two or three answer choices.
  • Good example: "What is your favorite fruit? Apple / Banana / Grape"
  • Bad example: "What do you think about things?" — too vague, no clear choices.

Step 2 — Collect the data

  • Ask each person your question and make one tally mark for their answer.
  • Ask at least 5 people.
  • Count the tally marks when everyone has answered.

Step 3 — Display in a bar graph

  • Draw a bar for each answer choice.
  • Make the bar as long as the tally total for that choice.
  • Give your graph a title and label each bar.

Step 4 — Draw a conclusion

  • Look at the data and say what you found out.
  • Example: "Most people in my family chose banana."
  • A conclusion is always based on the data — not just a guess.
