Unit 1 · Lesson 4 of 4 25 XP available

Welcome back, Detective! 🕵️

You asked a great question, built a survey, and collected clean data. Now for the best part: making the data talk. A good chart turns a pile of tally marks into a discovery anyone can see in two seconds.

Activity 1: Read the Story in a Chart

Another detective surveyed 21 classmates: "What's your favorite pet?" Read their bar chart, then answer the three questions.

1. Which pet is the most popular? (Detectives call this the mode.)

Cats Dogs Fish

2. How many classmates answered in total?

9 21 25

3. How many more kids chose dogs than fish?

3 9 6

Activity 2: Graph YOUR Data

Grab your tally sheet from Lesson 3. Pick one question, type in your answer choices and counts, and watch your bar chart draw itself!

Activity 3: Write Your Discovery

Every investigation ends with findings. Answer like a detective filing a report:

What did your data show? (Start with "Most people…" or "The most popular…")

Did it match the prediction you made in Lesson 2? What surprised you?
